Chapter 5: Presentation Organization

32 Purpose and Central Idea Statements

Speeches have traditionally been seen to have one of three broad purposes: to inform, to persuade, and — well, to be honest, different words are used for the third kind of speech purpose: to inspire, to amuse, to please, or to entertain. These broad goals are commonly known as a speech’s general purpose, since, in general, you are trying to inform, persuade, or entertain your audience without regard to specifically what the topic will be. Perhaps you could think of them as appealing to the understanding of the audience (informative), the will or action (persuasive), and the emotion or pleasure.

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose (to inform) and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge.

In writing your specific purpose statement, you will take three contributing elements (shown in figure 5.3) that will come together to help you determine your specific purpose :

You (your interests, your background, past jobs, experience, education, major),
Your audience
The context or setting.

Putting It Together

Keeping these three inputs in mind, you can begin to write a specific purpose statement , which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

To _______________ [Specific Communication Word (inform, explain, demonstrate, describe, define, persuade, convince, prove, argue)] my [ Target Audience (my classmates, the members of the Social Work Club, my coworkers] __________________. [T he Content (how to bake brownies, that Macs are better than PCs].

Example: The purpose of my presentation is to demonstrate for my coworkers the value of informed intercultural communication.

Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be. The statement that reveals your main points is commonly known as the central idea statement (or just the central idea). Just as you would create a thesis statement for an essay or research paper, the central idea statement helps focus your presentation by defining your topic, purpose, direction, angle and/or point of view. Here are two examples:

Specific Purpose – To explain to my classmates the effects of losing a pet on the elderly.

Central Idea – When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.

Specific Purpose – To demonstrate to my audience the correct method for cleaning a computer keyboard.

Central Idea – Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

16 Formulating a Central Idea Statement

While you will not actually say your specific purpose statement during your speech, you will need to clearly state what your focus and main points are going to be (preferably after using an introductory method such as those described in Chapter 8). The statement that reveals your main points is commonly known as the central idea statement (or just the central idea).

Now, at this point we need to make a point about terminology. Your instructor may call the central idea statement “the thesis” or “the thesis statement.” Your English composition instructor probably uses that term in your essay writing. Another instructor may call it the “main idea statement.” All of these are basically synonymous and you should not let the terms confuse you, but you should use the term your instructor uses.

That said, is the central idea statement the very same thing as the thesis sentence in an essay? Yes, in that both are letting the audience know with- out a doubt your topic, purpose, direction, angle and/or point of view. No, in that the rules for writing a “thesis” or central idea statement in a speech are not as strict as in an essay. For example, it is acceptable in a speech to announce the topic and purpose, although it is usually not the most artful or effective way to do it. You may say,

“In this speech I will try to motivate you to join me next month as a volunteer at the regional Special Olympics.”

That would be followed by a preview statement of what the speech’s arguments or reasons for participating will be, such as,

“You will see that it will benefit the community, the participants, and you individually.”

However, another approach is to “capsulize” the purpose, topic, approach, and preview in one succinct statement.

“Your involvement as a volunteer in next month’s regional Special Olympics will be a rewarding experience that will benefit the community, the participants, and you personally.”

This last version is really the better approach and most likely the one your instructor will prefer.

So, you don’t want to just repeat your specific purpose in the central idea statement, but you do want to provide complete information. Also, unlike the formal thesis of your English essays, the central idea statement in a speech can and should use personal language (I, me, we, us, you, your, etc.) and should attempt to be attention-getting and audience-focused.

And importantly, just like a formal thesis sentence, it must be a complete, grammatical sentence.

The point of your central idea statement in terms of your audience is to reveal and clarify the ideas or assertions you will be addressing in your speech, more commonly known as your main points, to fulfill your specific purpose. However, as you are processing your ideas and approach, you may still be working on them. Sometimes those main points will not be clear to you immediately. As much as we would like these writing processes to be straightforward, sometimes we find that we have to revise our original approach. This is why preparing a speech the night before you are giving it is a really, really bad idea. You need lots of time for the preparation and then the practice.

Sometimes you will hear the writing process referred to as “iterative.” This word means, among other things, that a speech or document is not always written in the same order as the audience finally experiences it. You may have noticed that we have not said anything about the introduction of your speech yet. Even though that is the first thing the audience hears, it may be one of the last parts you actually compose. It is best to consider your speech flexible as you work on it, and to be willing to edit and revise. If your instructor asks you to turn the outline in before the speech, you should be clear on how much you can revise after that. Otherwise, it helps to know that you can keep editing your speech until you deliver it, especially while you practice.

Here are some examples of pairs of specific purpose statements and central idea statements.

Specific Purpose: To explain to my classmates the effects of losing a pet on the elderly.

Central Idea: When elderly persons lose their animal companions, they can experience serious psychological, emotional, and physical effects.

Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard.

Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.

Specific Purpose: To persuade my political science class that labor unions are no longer a vital political force in the U.S.

Central Idea: Although for decades in the twentieth century labor unions influenced local and national elections, in this speech I will point to how their influence has declined in the last thirty years.

Specific Purpose: To motivate my audience to oppose the policy of drug testing welfare recipients.

Central Idea: Many voices are calling for welfare recipients to go through mandatory, regular drug testing, but this policy is unjust, impractical, and costly, and fair-minded Americans should actively oppose it.

Specific Purpose: To explain to my fellow civic club members why I admire Representative John Lewis.

Central Idea: John Lewis has my admiration for his sacrifices during the Civil Rights movement and his service to Georgia as a leader and U.S. Representative.

Specific Purpose: To describe how makeup is done for the TV show The Walking Dead.

Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice that in all of the above examples that neither the specific purpose nor the central idea ever exceeds one sentence. You may divide your central idea and the preview of main points into two sentences or three sentences, depending on what your instructor directs. If your central idea consists of more than three sentences, then you probably are including too much information and taking up time that is needed for the body of the speech. Additionally, you will have a speech trying to do too much and that goes overtime.

Central Idea

One method to help determining a central idea is to answer the specific purpose as though it leaves a question unanswered, such as why or what. If the specific purpose is “To inform the audience about the effects of mindfulness on health,” then the question unanswered by this statement is, what? What does the speaker want the audience to know about the effects of mindfulness on health in a single sentence? In other words, what is the central idea behind this purpose that will ultimately lead to achieving that goal?

Keep the central idea simple, yet focused. If preparing a 6- to 8-minute speech informing an audience of the causes for the Industrial Revolution, the central idea “The history of Western civilization is complex” would not work well. Such a central idea is too broad and vague, opening up the possibility to present a speech with far too much information for the speaker to cover in that short time period. Instead, the speaker should want a more specific central idea that more specifically summarizes the content of the speech, as the following example demonstrates:

“Beginning with Gutenberg’s printing press, the explosion of information-sharing in Western civilization led to rapid technological development.”

Helpful Hint

Students often struggle to determine if they have effectively stated their central idea as an assertion. Figure out by asking if someone could disagree with the central idea or develop a speech on a different perspective regarding the same topic.

For example, the central idea “Even with limited space, growing your own vegetables is easy and has many mental and physical benefits” could lead someone to present a different perspective on this topic and propose an alternate central idea such as: “Growing your own vegetables is a complex and challenging process that requires immense time and ample space.”

Referencing the specific purpose regarding the effects of mindfulness on health, an ideal central idea could look something like this: Developing mindfulness through regular practice produces benefits in all aspects of life, from mental health to physical well-being. Note that the sentence is complete, grammatically correct, asserts a perspective, and includes just enough information from which to derive the main points. From this single sentence, speakers can write a speech about mindfulness, the practices that nurture it, and the physical and mental benefits individuals might expect from doing so. This central idea, once written, supports the specific purpose and becomes the hinge around which everything else in the speech will revolve. Keep in mind that the central idea may need to remain flexible during the research phase of preparing the speech in order to tailor the information specifically to the audience. The specific purpose, regardless, remains the same. Different audiences may require different methods to relay the same message, so keep the central idea fluid until more information is known about their preferences.

8.2 The Topic, General Purpose, Specific Purpose, and Thesis

Before any work can be done on crafting the body of your speech or presentation, you must first do some prep work—selecting a topic, formulating a general purpose, a specific purpose statement, and crafting a central idea, or thesis statement. In doing so, you lay the foundation for your speech by making important decisions about what you will speak about and for what purpose you will speak. These decisions will influence and guide the entire speechwriting process, so it is wise to think carefully and critically during these beginning stages.

Understanding the General Purpose

Before any work on a speech can be done, the speaker needs to understand the general purpose of the speech. The general purpose is what the speaker hopes to accomplish and will help guide in the selection of a topic. The instructor generally provides the general purpose for a speech, which falls into one of three categories. A general purpose to inform would mean that the speaker is teaching the audience about a topic, increasing their understanding and awareness, or providing new information about a topic the audience might already know. Informative speeches are designed to present the facts, but not give the speaker’s opinion or any call to action. A general purpose to persuade would mean that the speaker is choosing the side of a topic and advocating for their side or belief. The speaker is asking the audience to believe in their stance, or to take an action in support of their topic. A general purpose to entertain often entails short speeches of ceremony, where the speaker is connecting the audience to the celebration. You can see how these general purposes are very different. An informative speech is just facts, the speaker would not be able to provide an opinion or direction on what to do with the information, whereas a persuasive speech includes the speaker’s opinions and direction on what to do with the information. Before a speaker chooses a topic, they must first understand the general purpose.

Selecting a Topic

Generally, speakers focus on one or more interrelated topics—relatively broad concepts, ideas, or problems that are relevant for particular audiences. The most common way that speakers discover topics is by simply observing what is happening around them—at their school, in their local government, or around the world. Opportunities abound for those interested in engaging speech as a tool for change. Perhaps the simplest way to find a topic is to ask yourself a few questions, including:

What important events are occurring locally, nationally, and internationally?
What do I care about most?
Is there someone or something I can advocate for?
What makes me angry/happy?
What beliefs/attitudes do I want to share?
Is there some information the audience needs to know?

Students speak about what is interesting to them and their audiences. What topics do you think are relevant today? There are other questions you might ask yourself, too, but these should lead you to at least a few topical choices. The most important work that these questions do is to locate topics within your pre-existing sphere of knowledge and interest. Topics should be ideas that interest the speaker or are part of their daily lives. In order for a topic to be effective, the speaker needs to have some credibility or connection to the topic; it would be unfair to ask the audience to donate to a cause that the speaker has never donated to. There must be a connection to the topic for the speaker to be seen as credible. David Zarefsky (2010) also identifies brainstorming as a way to develop speech topics, a strategy that can be helpful if the questions listed above did not yield an appropriate or interesting topic. Brainstorming involves looking at your daily activities to determine what you could share with an audience. Perhaps if you work out regularly or eat healthy, you could explain that to an audience, or demonstrate how to dribble a basketball. If you regularly play video games, you may advocate for us to take up video games or explain the history of video games. Anything that you find interesting or important might turn into a topic. Starting with a topic you are already interested in will make writing and presenting your speech a more enjoyable and meaningful experience. It means that your entire speechwriting process will focus on something you find important and that you can present this information to people who stand to benefit from your speech. At this point, it is also important to consider the audience before choosing a topic. While we might really enjoy a lot of different things that could be topics, if the audience has no connection to that topic, then it wouldn’t be meaningful for the speaker or audience. Since we always have a diverse audience, we want to make sure that everyone in the audience can gain some new information from the speech. Sometimes, a topic might be too complicated to cover in the amount of time we have to present, or involve too much information then that topic might not work for the assignment, and finally if the audience can not gain anything from a topic then it won’t work. Ultimately, when we choose a topic we want to pick something that we are familiar with and enjoy, we have credibility and that the audience could gain something from. Once you have answered these questions and narrowed your responses, you are still not done selecting your topic. For instance, you might have decided that you really care about breeds of dogs. This is a very broad topic and could easily lead to a dozen different speeches. To resolve this problem, speakers must also consider the audience to whom they will speak, the scope of their presentation, and the outcome they wish to achieve.

Formulating the Purpose Statements

By honing in on a very specific topic, you begin the work of formulating your purpose statement. In short, a purpose statement clearly states what it is you would like to achieve. Purpose statements are especially helpful for guiding you as you prepare your speech. When deciding which main points, facts, and examples to include, you should simply ask yourself whether they are relevant not only to the topic you have selected, but also whether they support the goal you outlined in your purpose statement. The general purpose statement of a speech may be to inform, to persuade, to celebrate, or to entertain. Thus, it is common to frame a specific purpose statement around one of these goals. According to O’Hair, Stewart, and Rubenstein, a specific purpose statement “expresses both the topic and the general speech purpose in action form and in terms of the specific objectives you hope to achieve” (2004). The specific purpose is a single sentence that states what the audience will gain from this speech, or what will happen at the end of the speech. The specific purpose is a combination of the general purpose and the topic and helps the speaker to focus in on what can be achieved in a short speech.

To go back to the topic of a dog breed, the general purpose might be to inform, a specific purpose might be: To inform the audience about how corgis became household pets. If the general purpose is to persuade the specific purpose might be: to persuade the audience that dog breeds deemed “dangerous” should not be excluded from living in the cities. In short, the general purpose statement lays out the broader goal of the speech while the specific purpose statement describes precisely what the speech is intended to do. The specific purpose should focus on the audience and be measurable, if I were to ask the audience before I began the speech how many people know how corgis became household pets, they could raise their hand, and if I ask at the end of my speech how many people know how corgis became household pets, I should see a lot more hands. The specific purpose is the “so what” of the speech, it helps the speaker focus on the audience and take a bigger idea of a topic and narrow it down to what can be accomplished in a short amount of time.

Writing the Thesis Statement

The specific purpose statement is a tool that you will use as you write your speech, but it is unlikely that it will appear verbatim in your speech. Instead, you will want to convert the specific purpose statement into a central idea, or thesis statement that you will share with your audience. Just like in a written paper, where the thesis comes in the first part of the paper, in a speech, the thesis comes within the first few sentences of the speech. The thesis must be stated and tells the audience what to expect in this speech. A thesis statement may encapsulate the main idea of a speech in just a sentence or two and be designed to give audiences a quick preview of what the entire speech will be about. The thesis statement should be a single, declarative statement followed by a separate preview statement. If you are a Harry Potter enthusiast, you may write a thesis statement (central idea) the following way using the above approach: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like story of a rise to fame.

Writing the Preview Statement

A preview statement (or series of statements) is a guide to your speech. This is the part of the speech that literally tells the audience exactly what main points you will cover. If you were to get on any freeway, there would be a green sign on the side of the road that tells you what cities are coming up—this is what your preview statement does; it tells the audience what points will be covered in the speech. Best of all, you would know what to look for! So, if we take our J.K Rowling example, the thesis and preview would look like this: J.K. Rowling is a renowned author of the Harry Potter series with a Cinderella-like rags-to-riches story. First, I will tell you about J.K. Rowling’s humble beginnings. Then, I will describe her personal struggles as a single mom. Finally, I will explain how she overcame adversity and became one of the richest women in the United Kingdom.

Writing the Body of Your Speech

Once you have finished the important work of deciding what your speech will be about, as well as formulating the purpose statement and crafting the thesis, you should turn your attention to writing the body of your speech. The body of your speech consists of 3–4 main points that support your thesis and help the audience to achieve the specific purpose. Creating main points helps to chunk the information you are sharing with your audience into an easy-to-understand organization. Choosing your main points will help you focus in on what information you want to share with the audience in order to prove your thesis. Since we can’t tell the audience everything about our topic, we need to choose our main points to make sure we can share the most important information with our audience. All of your main points are contained in the body, and normally this section is prepared well before you ever write the introduction or conclusion. The body of your speech will consume the largest amount of time to present, and it is the opportunity for you to elaborate on your supporting evidence, such as facts, statistics, examples, and opinions that support your thesis statement and do the work you have outlined in the specific purpose statement. Combining these various elements into a cohesive and compelling speech, however, is not without its difficulties, the first of which is deciding which elements to include and how they ought to be organized to best suit your purpose.

Reading Skills

Finding the central idea.

The Albert Team
Last Updated On: December 27, 2023

What We Review

Introduction

Understanding the central idea in reading is an essential skill for comprehending both literary and informational texts. Think of it as the heart of what the author wants to tell us. It’s not just the subject of the text but the key message or argument the author is presenting.

In articles or speeches, you might find this main idea in the first few sentences. But when it comes to novels or stories, it’s a bit like a puzzle. You’ll need to connect the dots throughout and sometimes even after you’ve finished reading to really grasp it.

In this blog post, we’re going to explore some great ways to identify this central idea, and we’ll try out some activities to practice this skill. Are you ready to get started? Let’s jump right in!

Defining Central Idea

The central idea of a text is not quite the same as the topic or theme. But that does not mean that both things are not important! In fact, being familiar with both the topic and theme is a stepping stone to grasping the central idea.

For example, take Shakespeare’s The Merchant of Venice . One of the initial topics is Antonio’s venture trading. Another possible topic is Antonio’s melancholy, but more is needed to understand the play’s central idea. As the play continues, the theme of Antisemitism is apparent in Antonio’s treatment of Shylock, the Jewish money-lender. However, there are so many other themes present! Love, deception, and marriage also feature – the theme alone does not accurately represent the central idea.

Looking at the play as a whole allows us to understand Shakespeare’s broader message about the human experience. For instance, a possible central idea in The Merchant of Venice is how it exposes the hypocrisy in both Christian and Jewish communities, showing how neither is morally superior despite their claims.

Additionally, a text can have several messages or central ideas expressed throughout the text, and Shakespeare is no exception to this.

The play suggests that these concepts are intertwined. In the climax, when Portia, disguised as a lawyer, serves justice to Shylock, it’s more than he bargained for. Meanwhile, Antonio, who was at risk of death, receives mercy. This twist of events highlights that mercy can sometimes be a form of justice, and vice versa, as seen when Antonio shows mercy to Shylock through his daughter, Jessica.

Strategies for Identifying the Central Idea

To find the central idea in a text, it’s essential to practice close reading , which means reading the text multiple times, each time with a different focus. Here’s how it works:

Preview the Text: Start by quickly going through the text to get a general idea of what it’s about. Look at things like headings, opening sentences, or any images or graphs.
First Reading – Basic Understanding: Now, read the text more thoroughly to understand what it’s saying. This is where you get a grip on the main topics and the basic storyline or arguments.
Second Reading – Deeper Understanding: Read the text again, but this time, pay attention to the key ideas and details. Think about how different parts of the text connect to each other.
Third Reading – Author’s Purpose and Perspective: In this reading, try to understand why the author wrote the text and their viewpoint. What are they trying to tell us? Why do they think this topic is important?
Identifying the Central Idea: After these readings, use everything you’ve gathered to figure out the central idea. This is where you put together the main messages from the text and understand what the author wants to say about life or the human experience.

By following these steps, you’ll be able to dive deep into a text and really understand not just what it’s about but what message the author is trying to convey.

Drawing Conclusions about the Central Idea

To accurately understand the central idea of a text, it’s important to analyze key elements systematically. Here’s a step-by-step approach:

Understand the Plot: Make sure you have a clear grasp of the story’s events. What happens and in what order?
Review the Characters: Focus on the characters, especially those who undergo significant changes. How and why do they change throughout the story?
Analyze Character Motivations and Actions: Consider what drives these characters. How do their motivations and actions highlight the main themes or key ideas in the text?
Link Themes to Character Development: Connect the dots between what motivates the characters and the broader themes of the story. This will help you form a clearer picture of the central idea.

For example, The Merchant of Venice characterizes Shylock as a greedy, vengeful money-lender bent on punishing Antonio for mistreating him. He maintains this character until he receives his verdict from Portia, which condemns him, instead of his enemy, for plotting to murder another Venetian. This verdict changes him into a sorrowful, broken man.

Shylock’s actions reveal that the theme of justice, in Shylock’s eyes, is merely vengeance. When Portia enters the scene, however, she brings with her the notion of the coexistence of justice and mercy. The final events of the play reveal the error of Shylock’s vengeance and how Shakespeare believed justice should be delivered alongside mercy.

Classroom Application

There are many things you can do to identify the central ideas in a text. Here are some tips to help you uncover the central idea in any text you’re reading:

Keep an Eye on the Characters: Pay attention to what the characters in the story are doing and why they’re doing it. As you read, jot down notes about their actions and motives. This will help you understand them better.
Back Up Your Ideas with Evidence: When you have a thought about a character or something that’s happening in the story, don’t just keep it in your head. Find a sentence or a scene in the book that supports your idea . This is like detective work – you’re finding clues to solve the mystery of the story’s main message.
Look for Themes: Themes are the big ideas in a story, like friendship, courage, or justice. Sometimes your teacher might give you a heads-up about what themes to look for. Keep track of parts of the story that show these themes. This is like collecting puzzle pieces to see the whole picture.
Put It All Together: Now for the cool part – take everything you’ve learned about the characters, their actions, and the themes, and mix it all together. This is where you start to see the bigger message the author is trying to tell us. It’s a bit like being a chef, combining ingredients to make an awesome dish.

Remember, figuring out the central idea isn’t just about spotting details – it’s about connecting them to form a bigger picture. And just like any skill, it gets easier and more fun the more you do it. So, dive into your next book and see what you can discover!

Module 9: Informative Speaking

Organizing the informative speech, learning objectives.

Discern the best organizational approach for types of informative speeches.

Like an essay, a speech should have a clear organizational structure with a recognizable beginning, middle, and end. But unlike an essay where your reader can go back and re-read sections they may not understand or follow, in a speech in front of a live audience your audience can’t stop, rewind, and re-listen to parts of your speech they didn’t follow. For that reason it is especially important to have a clear and easy-to-follow structure to a speech.

In this section, we introduce the characteristic organizational structures of an informative speech. Later on, we’ll explore each of the organizational structural elements in greater detail.

An informative speech can be broken up into three sections:

Section 1: Introduction. The first section of the speech contains an attention-getter to grab the interest of the audience and orient them to the topic of the speech, a clear thesis that states the purpose of the speech, and a preview of the main points of the speech.
Section 2: Body. The heart of the speech is the body. The body is where you provide your audience all the information they will need to understand your topic. To make the body of the speech easier for the audience to follow, divide it up into at least two but no more than five main points . Organize the main points in a clear structure appropriate to the topic and thesis and provide supporting examples and/or evidence for each main point.
Section 3: Conclusion. The conclusion is a short section that reinforces the thesis, summarizes the main points, and provides a sense of closure.

Video example

To see an example of an informative speech with a clear introduction, body, and conclusion, watch this speech where the speaker informs her audience how to manage the stress that comes with being a college student.

Specific Purpose Statement

Once you have a speech topic selected, develop a specific purpose statement. Your purpose statement describes what you want your audience to know as a result of listening to your speech. Here are some examples of informative speech purpose statements:

To inform my audience about different types of coffee makers.
To inform my audience about the historical significance of Harriet Tubman.
To inform my audience about how to prune roses.

Central Idea

Your purpose statement helps you determine the thesis or central idea of your speech. You will present your central idea in the introduction to the speech and everything you say in the speech will support that central idea.

For example, if your purpose is to inform your audience about different types of coffee makers you could develop a central idea like this:

There are two main types of coffee makers, automatic drip machines and manual coffee makers.

Main Points

Once you have a purpose statement you want to develop your main points. The body of the speech is where you will present and provide support for the main points of the speech. Remember that you should generally aim to have at least two but no more than five main points. Keep time constraints in mind when developing your main points. If you are given four minutes to speak, for instance, trying to have four main points might be too ambitious, so you might instead focus on two or at the most three main points.

You’ll want to organize the body of the speech in a way that helps you present your main points in the most effective order. Your purpose statement helps you decide what kind of organizational pattern would make the most sense for your topic.

Organizational Patterns

There are many types of organizational patterns you can use for an informative speech, as you can see in more detail in Module 6: Organizing and Outlining Your Speech. Here are a few examples:

In a topical organization structure, each point fits into one of a few topic categories.

Topical : This is a good, all-purpose organizational pattern where you divide your main points into topics. It works well for speeches where the main points are clearly distinct from each other and the order they are placed in isn’t critical like it would be for some other organizational patterns. The example above about coffee makers, for example, could be divided into two topical main points: 1) automatic drip coffee makers and 2) manual coffee makers. Each main point would be supported by subpoints that elaborate on the characteristics of each type of coffee maker.

Compare/contrast: With compare/contrast organizational patterns, you explain the similarities and differences between two or more things. A speech about the similarities and differences between video game consoles PlayStation and Xbox would fit this type of organizational pattern. You could devote one main point to the qualities they share in common and a second point to how they differ from each other.

A spatially organized speech about the Mississippi River might follow the river from north to south.

Spatial: Do you have a topic that lends itself to being explained in a directional order such as from top to bottom, left to right, or east to west? If so, you could organize your speech in a spatial pattern. This can be a good organizational pattern to use when you want to describe a place to an audience. For instance, if you gave a speech about the major cities the Mississippi River passes through you could start in the north by describing its origin in Minnesota near Minneapolis and St. Paul, then work south and explain how it flows through other cities like St. Louis before it empties into the Gulf of Mexico in New Orleans.

Chronological: This is a speech that follows a time order. This is a good choice for speeches where you want to explain a sequence of events. For example, you could use a chronological pattern for a speech explaining the steps Apple took in developing the iPhone or the significant decisions made by the Supreme Court affecting rights of the LGBTQIA community. Chronological can also be a good organizational choice for speeches where you are explaining a process or demonstrating how to do something.

Step by step description of how to draw an airplane

To describe or demonstrate a process, step by step may be the best structure.

Step-by-Step: When you’re speaking about a process, the most logical organizational structure may be step by step. Step-by-step organization is useful for “how-to” or demonstration speeches where you are teaching or showing how to do a task. If you were speaking about how to spray-paint a mural, you might describe each layer of the painting step by step.

Biographical : A biographical organization tells the story of a person’s life. The person could be a well-known person or someone who is not. The subject of the speech could even be the speaker themselves. It can be similar to the chronological pattern in that it can be organized by time but it doesn’t have to be. A biographical speech could start by focusing on an important event late in someone’s life and then going back in time to explain how the person got to that point.

A causal structure talks about why something happened.

Causal: If you want to explain a cause/effect relationship, you want to use the causal organizational pattern. Typically with this pattern, you would have two main points: one focused on the causes of an event, the second about its effects. A speech about hurricanes might be organized this way, for example. One main point could be devoted to oceanic and atmospheric causes of hurricanes and the second main point about the effects of hurricanes such as storm surge, strong winds, and flooding.

We cover outlining in detail elsewhere, but at this point once you have a purpose statement, general idea, main points, and an organizational pattern, you are ready to develop an outline.

Some important reminders about outlines:

Working outlines are what you start with and they help you with speech preparation and planning. This isn’t the outline you will use for speaking.
The full-sentence outline develops the full details of the message. But, again, it is not the outline you use to speak.
The speaking outline includes key words or phrases and helps you stay organized in front of the audience without reading to them. This is the outline you will speak from so that you are speaking extemporaneously rather than reading your outline word for word.
Tip: Using notecards for your speaking outline helps with delivery and makes it easier to find information if you lose your place or draw a blank.

Getting Started with Your Topic and Purpose

So far in this text we have examined many practical and theoretical aspects of public speaking as a method of communicating and as an art form. In this chapter we are going to get into the real meat of putting your speech together.

Often when we get to the point of sitting down to prepare a speech, we think about topics. That is understandable, but before we go any further, let’s recalibrate our minds to think also, or even more, about “purpose.” There are some benefits to considering purpose and topic simultaneously. Doing so will help you focus your speech to a manageable amount of content and become more audience-centered. Also, you will be able to make strategic decisions about other aspects of the speech, such as organization, supporting evidence, and visual aids.

Speeches have traditionally been seen to have one of three broad purposes: to inform, to persuade, and— Well, to be honest, different words are used for the third kind of speech purpose: to inspire, to amuse, to please, to delight, or to entertain. We will just use “to inspire” as the overall term here. These broad goals are commonly known as a speech’s general purpose , since, in general, you are trying to inform, persuade, or entertain/inspire your audience without regard to specifically what the topic will be. Perhaps you could think of them as appealing to the understanding of the audience (informative), the will or action (persuasive), and the emotion or pleasure.

Your instructor will most likely assign you an informative and a persuasive speech, and then perhaps one more. The third one might be a special occasion speech, such as a tribute (commemorative), an after-dinner speech, a toast, or a eulogy. These four types of speeches fit into the category of “to inspire” or “to entertain.” This text has sections on and examples of all three types.

It should be understood that these three purposes are not necessarily exclusive of the others. A speech designed to be persuasive can also be informative and entertaining, even if neither of those is the main purpose.

As we saw in Unit 1, the canons of rhetoric is the traditional way to explain the process of preparing a speech. That process is still a practical guide for today. The first canon, invention, or inventio , is discussed, at least in part, in this unit. Although in modern times we tend to think of invention as the creation of a new technology, invention basically means “discovery” of what to say.

The scholars of rhetoric from the ancient times encouraged the use of questions to “discover” the arguments and content of the speech. These were called “ topoi ” and there were a couple of dozen of them; modern scholars have reframed them as questions that can be used to develop reasons and material. These can be helpful in many ways, but here we will present just two basic questions you should consider for beginning your speech:

1. What value, connection, or interest does my purpose/topic have for the audience? What needs do they meet?

2. Why would the audience consider me, the speaker, a credible source on this purpose/topic?

We suggest that these two questions be in your mind as you develop your speech. You should answer them, directly or indirectly, for your audience in your speech. If your audience is unfamiliar with your topic, for instance, you would want to address the first one early in the speech. If your audience does not know anything about you, you should mention (in an appropriate way) your background in the subject area.

One of the authors has a core concept in her basic public speaking classes: The most effective speeches are the ones that answer the questions in the minds of the audience. She uses that to change the students’ focus from speaking just to express themselves to being audience-centered. She also uses the acronym “WIIFM.” This is not a new radio station, but the abbreviation for “What’s In It For Me?” The audience is asking this question, directly or indirectly, during a speech. Keep the WIIFM acronym in mind as you start to think about your speeches more and more from your audience’s perspective.

Formulating a Specific Purpose

Now that you know your general purpose (to inform, to persuade, or to entertain), you can start to move in the direction of the specific purpose. A specific purpose statement builds on your general purpose (such as to inform) and makes it more specific (as the name suggests). So if your first speech is an informative speech, your general purpose will be to inform your audience about a very specific realm of knowledge, for example, the history of NASA’s Shuttle program.

In writing your specific purpose statement, you will take three contributing elements that will come together to help you determine your specific purpose. The diagram shows those three elements. These three elements are you (your interests, your background, past jobs, experience, education, major), your audience (which you learned to analyze later), and the context or setting (also discussed later).

An old adage states, “Write about what you know.” In many ways, that is a great place to start with creating a speech, although you will need to consult other sources as well. If you start with ideas that reflect your interests, goals, and passions, that passion and commitment will come across in your speech, give you more credibility in the eyes of your audience, and make your speech more interesting.

This would be a good place for you to do an inventory. Retail stores do regular inventories to know what is “really there” in the stores. You have much more going on in your brain and background than you can be conscious of at any one time. Being asked the right kinds of prompts can help you find ideas. Below is a list of prompts for this inventory. To help generate some ideas for your speeches, complete the phrases and/or answer the questions below to see if any ideas can be generated from experiences or interests you may not have realized you had.

This inventory may seem long and intrusive, but digging a little deeper may help you find ideas and directions that are unique to you. You want to find this kind of subject matter and not the same topics others will gravitate towards just because they saw a list on Google on informative speech topics. Also, generating your list based on these questions and prompts will get you excited about your topic and talking about it to your classmates. For example, a very common persuasive speech topic is organ donation. There is nothing wrong with that topic per se and it is an important issue. However, if you ask yourself the right questions, you may come up with something far more central to who you are and that might interest and/or apply to the audience more.

Another approach that you might find helpful is to determine what you are passionate about through two binary routes. First, you will obviously be passionate about the things you love, so talk about those. Is The Simpsons your favorite TV show? Then you can inform us on the people and vision of the team behind this highly popular and long-running TV show. Do you feel that Big Brothers Big Sisters is a vital organization in the way it helps kids? Then persuade us to volunteer there. Conversely, you can also be passionate about things you don’t love (i.e., hate). Does it really annoy you when people don’t use their turn signals? Then persuade us to always use them. Do you want to scream when you hear a cell phone go off at the movies? Then persuade us that cell phones should be banned in theaters.

The Audience

Of course, what you love or hate may be in stark contrast to how your audience feels, so it is important to keep them in mind as well, which brings us to the next contributing factor. After you examine what you know and are passionate about, you have to determine if and how the topic has practical value or interest for others. It may be that it is a topic the audience is not immediately interested in but needs to know about for their own benefit. Then it becomes necessary for you to find that angle and approach that will help them see the benefit of the topic and listen to you. The more you know about your audience, the better you can achieve this goal. Good speakers are very knowledgeable about their audiences.

The Context

Many aspects come into the context of a speech, but the main ones are the time, place, and reason(s) for the event and the audience being there. Your classroom speeches have a fairly set context: time limits, the classroom, assignment specifications. Other speeches you will give in college (or in your career and personal life) will require you to think more deeply about the context just as you would the audience.

Putting It Together

Keeping these three inputs in mind, you can begin to write a specific purpose statement, which will be the foundation for everything you say in the speech and a guide for what you do not say. This formula will help you in putting together your specific purpose statement:

Specific Communication (to inform, to explain, to demonstrate, to describe, to define, to persuade, to convince, to prove, to argue)
Target Audience (my classmates, the members of the Social Work Club, my coworkers)
The Content (how to bake brownies, that Macs are better than PCs)

Each of these parts of the specific purpose is important. The first two parts make sure you are clear on your purpose and know specifically who will be hearing your message. However, we will focus on the last part here.

The content part of the specific purposes statement must first be singular and focused, and the content must match the purpose. The word “and” really should not appear in the specific purpose statement since that would make it seem that you have two purposes and two topics. Obviously, the specific purpose statement’s content must be very narrowly defined and, well, specific. One mistake beginning speakers often make is to try to “cover” too much material. They tend to speak about the whole alphabet, A-Z on a subject, instead of just “T” or “L.” This comes from an emphasis on the topic more than the purpose, and from not keeping audience and context in mind. In other words, go deep (specific), not broad. Examples in this chapter will show what that means.

Second, the content must match the focus of the purpose word. A common error is to match an informative purpose with a persuasive content clause or phrase. For example,

To explain to my classmates why term life insurance is a better option than whole life insurance policies.

To inform my classmates about how the recent Supreme Court decision on police procedures during arrests is unconstitutional.

Sometimes it takes an unbiased second party to see where your content and purpose may not match.

Third, the specific purpose statement should be relevant to the audience. How does the purpose and its topic touch upon their lives, wallets, relationships, careers, etc.? It is also a good idea to keep in mind what you want the audience to walk away with or what you want them to know, to be able to do, to think, to act upon, or to respond to your topic—your ultimate outcome or result.

To revisit an earlier example, “to explain to my classmates the history of NASA” would be far too much material and the audience may be unsure of its relevance. A more specific one such as “to inform my classmates about the decline of the Shuttle program” would be more manageable and closer to their experience. It would also reference two well-known historical tragedies involving the Shuttle program, the Challenger Disaster in 1986 and the Columbia Explosion in 2003. Here are several examples of specific purposes statements. Notice how they meet the standards of being singular, focused, relevant, and consistent.

To inform my classmates of the origin of the hospice movement.

To describe to my coworkers the steps to apply for retirement.

To define for a group of new graduate students the term “academic freedom.”

To explain to the Lions Club members the problems faced by veterans of the wars in Iraq and Afghanistan.

To persuade the members of the Greek society to take the spring break trip to Daytona Beach.

To motivate my classmates to engage in the College’s study abroad program.

To convince my classroom audience that they need at least seven hours of sleep per night to do well in their studies.

Now that you understand the basic form and function of a specific purpose statement, let’s revisit the original diagram in this section. The same topic for a different audience will create a somewhat different specific purpose statement. Public speaking is not a “one-size-fits-all” proposition. Let’s take the subject of participating in the study abroad program. How would you change your approach if you were addressing first-semester freshmen instead of first-semester juniors? Or if you were speaking to high school students in one of the college’s feeder high schools? Or if you were asked to share your experiences with a local civic group that gave you a partial scholarship to participate in the program? You would have slightly different specific purpose statements although your experience and basic information are all the same.

For another example, let’s say that one of your family members has benefited from being in the Special Olympics and you have volunteered two years at the local event. You could give a tribute (commemorative speech) about the work of Special Olympics (with the purpose to inspire), an informative speech on the scope or history of the Special Olympics, or a persuasive speech on why audience members should volunteer at next year’s event. “Special Olympics” is a key word in every specific purpose, but the statements would otherwise be different.

Despite all the information given about specific purpose statements so far, the next thing you read will seem strange: Never start your speech by saying your specific purpose to the audience. In a sense, it is just for you and the instructor. For you, it’s like a note you might tack on the mirror or refrigerator to keep you on track. For the instructor, it’s a way for him or her to know you are accomplishing both the assignment and what you set out to do. Avoid the temptation to default to saying it at the beginning of your speech. It will seem awkward and repetitive.
