bandy (v.)[bandy 词源字典]: 1570s, "to strike back and forth," from Middle French bander, from root of band (n.2). The sense apparently evolved from "join together to oppose," to opposition itself, to "exchanging blows," then metaphorically, to volleying in tennis. Bandy (n.) was a 17c. Irish game, precursor of field hockey, played with a curved stick (also called a bandy), hence bandy-legged (1680s).[bandy etymology, bandy origin, 英语词源]
sambo (n.1): "person of mixed blood in America and Asia," 1748, perhaps from Spanish zambo "bandy-legged," probably from Latin scambus "bow-legged," from Greek skambos. Used variously in different regions to indicate some mixture of African, European, and Indian blood; common senses were "child of black and Indian parentage" and "offspring of a black and a mulatto."
valgus (adj.): deformity in which a bone or joint is twisted outward from the center of the body; form of club-foot, 1800, from Latin valgus "bandy-legged, bow-legged, having the legs bent outward." Said to be probably related to Sanskrit valgati "to move up and down," Old English wealcan "to roll, move to and fro" (see walk (v.)), perhaps on the notion of "go irregularly or to and fro" [Tucker]. "Yet the main characteristic of 'bow-legged' is the crookedness of the legs, not 'going up and down' or 'to and fro'" [de Vaan] and there are phonetic difficulties. A classical word used in a different sense in modern medicine; also see varus.
