Etymology: The Latin "cōnsummātor" meant "one who completes or perfects something," built from the verb "cōnsummāre," "to sum up, finish, or bring to completion." The English word took its shape from that Latin root, and its sense of a person or thing that brings an undertaking to its final purpose follows directly from that idea of finishing a task fully. English also gave the word a familiar partner: "consummate," the adjective meaning "complete" or "accomplished," which the noun is built on. Adding the suffix "-or," which marks someone or something that performs an action, turns the idea of completing into the idea of the agent who completes.

Synonyms: completer, finisher

Antonyms: incomplete, unfinished
