Recorded since c.1420 as Middle English marin, borrowed from Middle French marin, from Old French, from Latin marinus (“of the sea”), itself from mare (“sea”), from Proto-Indo-European móri (“body of water, lake”) (cognate with Old English mere (“sea, lake, pool, pond”), Dutch meer, German Meer, all from Proto-Germanic mari). The modern pronunciation is presumably due to the influence of modern French marine, feminine singular of marin.
