acolyte (n.)

early 14c., "inferior officer in the church," from Old French acolite or directly from Medieval Latin acolytus (Late Latin acoluthus), from Greek akolouthos "following, attending on," as a noun, "a follower, attendant," literally "having one way," from a- "together with," copulative prefix (see a- (3)), + keleuthos "a way, road, path, course, journey," which is of unknown etymology. The word was in late Old English as acolitus, a Latin form; in early modern English a corrected form acolythe was used.
