bribe (n.)
late 14c., "thing stolen," from Old French bribe "bit, piece, hunk; morsel of bread given to beggars" (14c., compare Old French bribeor "vagrant, beggar"), from briber, brimber "to beg," a general Romanic word (Gamillscheg marks it as Rotwelsch, i.e. "thieves' jargon"), of uncertain origin; old sources suggest Celtic (compare Breton breva "to break"). Shift of meaning to "gift given to influence corruptly" is by mid-15c.
bribe (v.)
late 14c., "pilfer, steal," also "practice extortion," from Old French briber "go begging," from bribe (see bribe (n.)). Related: Bribed; bribing.
