From Middle English sergeant, sergeaunt, serjent, serjaunt, serjawnt, sergant, from Old French sergeant, sergent, serjant, sergient, sergant (“sergeant, servant”), from Medieval Latin servientem, accusative of serviēns (“a servant, vassal, soldier, apparitor”), from Latin serviēns (“serving”), present participle of serviō (“serve, be a slave to”). Doublet of servant and servient. The shift from /vj/ > /dʒ/ was a regular development in Old French. Compare cavea > cage, salvia > sage. The fish is so called because of its stripes, supposed to resemble a sergeant's insignia of rank. The pronunciation with /ɑɹ/ is due to a widespread development of Middle English er + consonant (see barn, start etc.). In sergeant, the spelling was standardised in one way, the pronunciation in another (compare clerk, derby in Commonwealth English, further parson vs. person, and varsity vs. university).
