masc. proper name, from Old French Andreu (Modern French André), from Latin Andreas, from Greek Andreas, from andreios "manly," from aner (genitive andros) "man" (see anthropo-). Andrew Millar (1590s) for some forgotten reason became English naval slang for "government authority," and especially "the Royal Navy." St. Andrew (feast day Nov. 30) has long been regarded as patron saint of Scotland. The Andrew's cross (c. 1400) supposedly resembles the one St. Andrew was crucified on.[Andrew etymology, Andrew origin, 英语词源]
