What it means
きっと is an adverb meaning “surely” or “certainly.” It shows the speaker’s strong belief or expectation that something is true or will happen. It often describes a future event or a guess based on available information, but it does not always express absolute certainty. It is placed before the clause or predicate it modifies.
Usage note
きっと is stronger than a simple guess, but it can still be wrong. Do not confuse it with ぜったいに, which often expresses a firmer promise, prohibition, or determination.
