What is opposite for girl?

Answer 1

Some words do not have opposites. Generally those that do have opposites are adjectives or adverbs (fast vs. slow, rich vs. poor). Nouns often do not have opposites (e.g. there is no opposite for apple, steak, wine bottle). Girl follows that case. A girl is not the opposite of a boy. A girl is a young female human being, a boy is a young male human being. They are only different in one of the adjectives used to describe them, this does not make them opposite.

Answer 2

Female, girl, or women. Those are opposites of guy.

Answer 3
