Word History

Etymology

borrowed from French complicité, borrowed from New Latin complicitāt-, complicitās, formed from Late Latin complic-, complex "fellow-participant, partner, accomplice" and Latin -itāt-, -itās -ity, probably after Late Latin duplicitās duplicity — more at complice

Note: The formation of the word is peculiar in that Latin -itāt-, -itās, along with its descendants and borrowings, is rarely added to nouns. Outside of the dictionaries of Thomas Blount and Elisha Coles, complicity is rare to non-existent in English text before the later eighteenth century, when its adoption was probably stimulated by French complicité.

First Known Use

circa 1656, in the meaning defined at sense 1
