Usage and Meaning

The verbs “think” and “believe” both relate to the way we hold ideas or opinions, but they are used slightly differently.
  • Think is used for opinions or ideas that are based on reasoning, observation, or guesswork. It often suggests that the person has considered the situation.
  • Believe is used for ideas or feelings that someone accepts as true, often without proof. It can express stronger conviction or faith.

Grammar Rules

Think

  • Can be followed by:
    • A clause (using that): *I think that it’s going to rain.
    • A question word: *I think where they went is unknown.
    • A noun or pronoun + infinitive: *I think him to be honest.
  • Can be used with modal verbs (e.g., I think he might be late.)

Believe

  • Is usually followed by a clause (using that): *I believe that she will succeed.
  • Can be followed by a noun phrase: *I believe him.

Differences in Usage
