Word Origin & History
lout1540s, "awkward fellow, clown, bumpkin," perhaps from dialectal derivative of O.E. verb lutan "bow low," from P.Gmc. *leut- "to bow, bend, stoop" (cf. O.N. lutr "stooping"), from PIE *leud- "to lurk" (cf. Goth. luton "to deceive," O.E. lot "deceit), also "to be small" (see
little). Non-Germanic cognates probably include Lith. liudeti "to mourn;" O.C.S. luditi "to deceive," ludu "foolish." Sense of "cad" is first attested 1857 in British schoolboy slang.
