Word Origin & History
babble
1230, babeln "to prattle," akin to other Western European words for stammering and prattling (cf. Swed. babbla, Fr. babiller) attested from the same era, some of which were probably borrowed, but etymologists cannot now determine which were original. Probably imitative of baby-talk, in any case (cf. L. babulus, Gk. barbaros). "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.1418.
