chatterbox

/ˌtʃædərˈbɑks/

/ˈtʃætəbɒks/

Other forms: chatterboxes

A chatterbox is a person who tends to use a whole lot of words without having much of anything to say. If you're constantly whispering to your friend during math class, your annoyed teacher might call you a chatterbox.

The informal word chatterbox is the perfect term for the annoying, incessant talker you always seem to end up sitting next to on long plane trips. Chatterbox dates from the 1770s, a combination of chatter, an echoic or onomatopoeic word, and box, giving chatterbox the sense of "a box or container full of idle chatter."
