felon
1297, from O.Fr. felon "wicked person, traitor, rebel," from M.L. fellonem "evil-doer," of uncertain origin, perhaps from Frank. *fillo, *filljo "person who whips or beats, scourger" (cf. O.H.G. fillen "to whip"); or from L. fel "gall, poison," on the notion of "one full of bitterness." Another theory (advanced by Professor R. Atkinson of Dublin) traces it to L. fellare "to suck", which had an obscene secondary meaning in classical L. (well-known to readers of Martial and Catullus), which would make a felon etymologically a "cock-sucker." OED inclines toward the "gall" explanation, but finds Atkinson's "most plausible" of the others.
