Explanation
Definitely means without any doubt, for sure, or certainly. It is used to show something is true or will surely happen. For example, if a friend asks, “Are you joining the company for dinner?” you might answer, “Definitely!” It makes a statement stronger and clearer. It is the opposite of “maybe.” People often use it in speech to agree or to confirm a plan, like saying, “That book was definitely the best one I’ve ever read”.
