Word History

Etymology

borrowed from Anglo-French acomplice, alteration of complice "associate" — more at complice

Note: The source of initial a(c)- is unclear. The earlier notion that a- represents fusion of the indefinite article cannot be maintained given the much earlier occurrences of the word in Anglo-French (in a 1384 petition of the Drapers guild, and in vol. 2 of the Rotuli Parliamentorum [1279-1377]). The suggestion that complice has been assimilated to accomplir, "to fulfill, etc.," (see accomplish) is not very compelling semantically.
