  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.

Chambers 20th Century Dictionary

  1. Complement

    kom′ple-ment, n. that which completes or fills up: full number or quantity: (Shak.) politeness.—v.t. Complement′, to supplement: (arch.) to compliment.—adjs. Complement′al, completing: (Shak.) complimental; Complement′ary, completing: together making up a whole.—Complementary angles, angles which together make up a right angle. [L. complementumcom, and plēre, to fill.]
