How To Essays

Do you know how to do something? Would you like to teach other people how to do it? How-to essays are fun to write and easy if you already feel you are an expert on a particular topic. Look at the list below for ideas, and also brainstorm by making a list of things you already know how to do.

Know Your Audience: You can vary the way you write this topic depending on who your audience is. For instance, depending on the knowledge of your audience, you can write several different essays on the simple topic of “How to Shoot a Free Throw":

  1. Free Throw 101 for Elementary School Students
  2. Teaching Middle School Players How to Shoot a Free Throw
  3. Pro Tips for High School Players on Shooting Free Throws
  4. How to Shoot a Free Throw After a Shoulder Injury

Use your title to narrow down your subject and your audience. Generally, you will aim for an audience who knows less than you do about that topic or someone who is at your same level but doesn't know the specific information you can teach them.

Definition Essay Ideas

In order to write a Definition or Concept essay, you will need to think about the different parts or aspects of your subject. By taking the concept apart and describing the different parts, it helps us to understand the whole more completely.

Although this sort of writing is not written as an argument, these essays do usually involve your opinion. How? As you define something, you often are arguing how we should define something or how people ought to see a concept. These sorts of essays can be on more general concepts everyone already knows (love, beauty, peace, friendship) or might also explain a specialized vocabulary only used by people in a particular hobby or job (zesting in cooking, bulb planting in gardening).

Cause and Effect Essays

This essay asks you to explain the reason for a trend (or a one-time event) or a phenomenon (a trend which is increasing in popularity). Generally, a good cause topic doesn't have an easy explanation and may be something that people argue about. In fact, your essay doesn't have to have the answer for the cause or effect.

Process Essay Topic Ideas

Like the How-to essay, the Process essay explains how something occurs in time. However, rather than telling the reader how to do it, the process essay explains how it is observed to happen. You can use this sort of essay to explain something that happens in nature, science, or society. These sorts of essays are easy to organize because the order of the essay is the way it happens. However, the writer does need to carefully decide how to explain the process clearly and vividly to make it interesting.

History or Background Essays

History or background essays take a look at the progression through time of an idea, movement, political decision, social phenomenon, or event. This sort of writing can be used to discuss the process of natural events, as well. Often, these papers discuss the facts as they occurred and may suggest causes and effects in the chain of events.

How Much History?

Often, the subjects can be big enough for several large books, so in a short piece, you may want to tackle just one part of that event. For example, a "History of Marriage" could look at the major changes in marriage as people moved from primitive societies to towns and then into the industrial age. Alternatively, a "History of Modern Marriage" could examine just the changes in marriage in the past few generations.

  1. What is the history of marriage?
  2. What is the history of divorce in America?
  3. What is the history of the Civil Rights Movement (or abolitionism or temperance)?
  4. What is the history of the Tea Party (or another political movement)?
  5. What is the history of the feminist movement (or the movement to get the vote for women)?
  6. What is the history of the Black Lives Matter movement?
  7. What is the history of the Nanjing Massacre (or any other war atrocity)?
  8. What is the history of the tensions between China and Taiwan (or any other two countries in tension)?
  9. What is the history of the U.S.'s stance toward illegal immigrants?
  10. What is the history of how football became the favorite national sport in the U.S.?
  11. What is the history of the Branch Davidians in Waco (or another cult group)?
  12. What is the geological history of Texas (or any other part of the world)?
  13. What is the history of the creationism vs. evolution debate in the United States?
  14. What is the history of the homeschooling movement (or charter schools, or vouchers)?
  15. What is the history of the Libertarian Party (or other political party) in the United States?
  16. What is the history of Greenpeace (or another ecology movement)?
  17. What is the history of the translation of the Bible into other languages?
  18. What is the history of coffee (or tea, Dr. Pepper, or Coke)?
  19. What is the history of the development of computers (or binary code, or computer language)?
  20. What is the history of women's swimwear (or other fashion)?
  21. What is the history of the development of state lotteries in the U.S.?

Questions & Answers

  • How would one write the introduction to this kind of assignment essay question: "Define probability sample and describe the various types of probability samples"?

    This type of explaining essay is technical, and so a straightforward introduction is probably the best. You can start with a clear definition, or possibly, you might want to give one or more examples of probability samples, and then give the definition.

  • What do you think of the topic, "How has the English language been spread globally?" for an explanation essay?

    Looking at the history of English and England's colonialism will give you answers to that question. English is also able to adapt and add words from other languages very easily. Here are some similar questions:

    1. Why is English in Britain different from that in America, Canada, and Australia?

    2. Why is English the universal language of science?

    3. Will Mandarin or another language ever supplant English as the global language?

  • How would one write the body of an explaining essay on the topic "designing a primary school library?"

    An explaining essay is usually divided either into sections or topics, or by space and time. I think with the topic of designing a school library; you should do it by parts of the library or aspects of the library. For example, you could do body paragraphs on the following topics:


    different book sections and book shelving

    checkout counter and equipment

    entrance and exit

    traffic flow

    places students can read

    See my article on how to write an Explaining Essay: https://hubpages.com/academia/How-to-Write-an-Expl...

  • What do you think of the essay topic "What does "Prabandha" mean?"

    Since Prabandha is a medieval Indian Sanskrit literary genre, you probably need to be a bit more specific about what "meaning" you are talking about. Try these topics:

    1. What is the importance of Prabandha?

    2. How is Prabandha similar to other medieval writing?

    3. What is Prabandha?

    4. How does Prabandha influence people today?

    5. Which saying or anecdotes from Prabandha have had the most influence in Indian culture?

  • Why does netball have so many rules?

    That topic question is a "cause" essay. If your assignment is writing an explaining essay, a better question would be one of the following:

    1. What are the rules of netball?

    2. How is netball played?

    3. What makes netball different from other games?

      I totally agree, Virginia--when I was reading through the lists, I was thinking--hmm--hubs!! Definitely great information for those folks who need to come up with essay topics. I always think that that is the hardest part of writing anything--just knowing what to call it or title it in the case of hubs--and then the ideas start to kind of flow--once you pin down where you want to go. Great presentation and fantastic pictures/ideas~
