  1. Complement

    In grammar and linguistics, the term complement is used with different meanings, so it is difficult to give a single precise definition and explanation. In a broad general sense however, a complement can be understood as a word, phrase or clause that is necessary to complete the meaning of a given expression. The terms complement and argument overlap in meaning and use. A given complement is therefore often also an argument. Complements are not adjuncts, however.
