Why Use More Precise Verbs of Thought?

Using a wider range of verbs helps you express yourself more accurately in English. Think そして know are general verbs, but they don’t always show the specific way you are thinking or knowing.

More precise verbs add detail and nuance to your sentences. They tell the listener or reader how you arrived at an idea or what kind of knowledge you have.

Expressing Beliefs and Certainty

These verbs describe how you form opinions or what you believe to be true.

• Assume: To believe something is true without definite proof, often based on little information. You take it for granted.
• Come to the conclusion: To decide something after thinking about it carefully or considering all the facts. It’s a result of a thought process.
• Doubt: To feel uncertain about something or to believe that something is probably not true. You have reservations.

Expressing Awareness and Understanding

These verbs relate to becoming conscious of facts or ensuring information is correct.

• Realise: To understand or become aware of a fact or situation, often suddenly. It’s a moment of insight.
• Be aware: To know about something, especially a situation or fact. It means having knowledge or information.
• Make sure: To take action so that something definitely happens or is true. You check or confirm something.
• Not have any idea / Have no idea: To not know something at all. It expresses complete lack of knowledge.

Expressing Uncertainty and Estimation

These verbs are used when you are unsure, questioning, or making an educated guess.

• Wonder: To ask yourself questions about something or to express a desire to know. You are curious.
• Estimate: To guess the size, amount, or value of something, often without exact calculation but based on some information.

スペイン語話者がよく犯す間違い

Spanish speakers sometimes overuse think when a more specific verb is needed. For example, directly translating ‘pensar’ can lead to:

• Incorrect: I thought she was famous in her country.

  正しい： I assumed she was famous in her country. (If you believed it without proof)

• Incorrect: I didn’t think who they were.

  正しい： I had no idea who they were. (For complete lack of knowledge)

Another common error is confusing realise (darse cuenta) with achieve または perform (realizar). Remember, realise means to become aware or understand, not to accomplish something.
