The adjective is borrowed from Latin supīnus, from sup- (see sub (“under”)) + -īnus (“of, pertaining to”). The word is cognate with Catalan supí, Italian supino, Old French sovin, Middle French souvin, Anglo-Norman supin, Old Occitan sobin, sopin, Portuguese supino, Spanish supino. Partly displaced upweard, whence Modern English upward. The noun is from Late Middle English supin (“supine of a Latin verb”) or Middle French supin (“(grammar) supine”), from Latin supīnum, (ellipsis of supīnum verbum (“supine verb”)), from supīnus; further etymology above.
