Word History: The word flunky has come into Standard English from Scots, in which the word meant "liveried manservant, footman," coming at least by the 19th century to be a term of contempt. The word is first recorded and defined in a work about Scots published in 1782. The definition states that a flunky is "literally a sidesman or attendant at your flank," which gives support to the suggestion that flunky is a derivative and alteration of flanker, "one who stands at a person's flank."
1782, Scottish dial., "footman, liveried servant," of uncertain origin, perhaps a dim. variant of flanker. Sense of "flatterer, toady" first recorded 1855.
