English Vocabulary Lesson – Suppose vs. Guess vs. Figure

Michael Vocabulary 2 Comments

Building up your vocabulary is essential when you are learning a second language. In this English lesson, let’s look at the difference between suppose, guess, and figure. This will help you in your everyday English conversations, as well as on English tests such as the TOEIC exam.

Suppose means to assume something, based on some evidence or probability, but without certain proof:

  • I suppose you have a good reason for being late. I’m sure you probably have a good reason for being late.
  • It’s 6:10pm and nobody answered the phone in Joe’s office. I suppose they’ve already gone home. I know they usually go home by 5:30 or 6:00pm. Based on that, and the evidence that nobody answered the phone, I assume they’ve already gone home. 

We also use suppose to introduce a hypothesis:

  • The police suppose the bank was robbed between 9pm Friday and noon on Saturday.
  • I suppose we could attract more customers by changing the color of the website.

Guess means to estimate something without having sufficient information to be exactly correct:

  • I guess Jane’s boyfriend is about 35 or 37 years old.
  • There’s a long line in front of the restaurant. I guess there will be a long wait for a table.

Figure is used in informal English to mean we think or expect something to be the situation:

  • The boss said he wants to talk about something important tomorrow. I figure he will talk to me about that transfer to Tokyo I heard about. The transfer to Tokyo is a big topic in my company now, and I since only a few of us speak Japanese, think the boss wants to talk about this.
  • I cooked dinner! I figured you would be tired from your long day in the office, so I decided to cook dinner for you. I expected that you would be too tired to cook.

Keep in mind the best way to remember this or any vocabulary in English is to take the word or phrase write it in a sentence that’s true for you or true in your world and then memorize your sentences.

You can even take your sentences and write them in the comments below. I would love to see your examples. And if you really want help with vocabulary, sign up for my free vocabulary workshop (see below).
