Why turkey has the same name as Turkey
mid-13c., babeln "to prattle, chatter," akin to other Western European words for stammering and prattling (cf. Swedish babbla, Old French babillier) attested from the same era, some of which probably were borrowed from others, but etymologists cannot now determine which were original. Probably imitative of baby-talk, in any case (cf. Latin babulus "babbler," Greek barbaros "non-Greek-speaking"). "No direct connexion with Babel can be traced; though association with that may have affected the senses" [OED]. Meaning "to repeat oneself incoherently, speak foolishly" is attested from c.1400. Related: Babbled; babbling.
"idle talk," c.1500, from babble (v.). In 16c., commonly in reduplicated form bibble-babble.
