From Middle English leg, legge, from Old Norse leggr (“leg, calf, bone of the arm or leg, hollow tube, stalk”), from Proto-Germanic *lagjaz, *lagwijaz (“leg, thigh”) (see it for more). Cognate with Scots leg (“leg”), Icelandic leggur (“leg, limb”), Norwegian Bokmål legg (“leg”), Norwegian Nynorsk legg (“leg”), Swedish lägg (“leg, shank, shaft”), Danish læg (“leg”), Lombardic lagi (“thigh, shank, leg”), Latin lacertus (“limb, arm”), Persian لنگ (leng). Upon borrowing, mostly displaced the native Old English term sċanca (Modern English shank).
