Untuck → It is formed from "un-" (meaning not or opposite of) and "tuck" (from Old French *toquer*, meaning to fold or tuck in). The word "untuck" means to remove the folds or to release something that has been tucked in.
Think of 'un-' meaning not or opposite, and 'tuck' meaning to fold something in. So, when you untuck something, you are releasing it from being folded in.
