From Italian complire, Catalan complir (“to complete, fulfil; to carry out”), Spanish cumplir (“to complete, fulfil”), (alternatively from Old French compli), from Latin complēre, from compleō (“to finish, complete; to fulfil”), from com- (prefix indicating completeness of an act) (ultimately from Proto-Indo-European ḱóm (“beside, near; by, with”)) + pleō (“to fill; to fulfil”) (ultimately from Proto-Indo-European pleh₁- (“to fill”)). The word is very close to the French verb complaire which means to satisfy or to please. The word is also cognate with Old French complir (“to accomplish, complete; to do”) (modern French accomplir (“to accomplish, achieve”)). Compare complete, compliment.
The verb is intransitive and almost always takes the preposition 'with' before the object.
