flibbertigibbet

Flibbertigibbet is one of many incarnations of the Middle English word flepergebet, meaning "gossip" or "chatterer" (others include flybbergybe, flibber de' Jibb, and flipperty-gibbet). It is a word of onomatopoeic origin, created from sounds that were intended to represent meaningless chatter. William Shakespeare apparently saw a devilish aspect to a gossipy chatterer; he used flibbertigibbet in King Lear as the name of a devil. This use never caught on, but the devilish connotation of the word reappeared over 200 years later when Sir Walter Scott used Flibbertigibbet as the nickname of an impish urchin in the novel Kenilworth. The impish meaning derived from Scott's character was short-lived and was laid to rest by the 19th-century's end, leaving us with only the "silly flighty person" meaning.
