Expressing Certainty and Uncertainty

In English, we express different levels of certainty using modal verbs and expressions. This is important for academic writing and discussion.

Expressing Certainty

• 100% certainty: must, cannot, definitely, certainly.
• Example: “He must be at home. The lights are on.”

Expressing Probability

• Strong probability: should, ought to, likely to.
• Medium probability: may, might, could, perhaps, maybe.
• Weak probability: might, could (doubtful), unlikely.

Expressing Uncertainty

• I’m not sure if/whether…
• It is uncertain/unclear whether…
• There is doubt about…
