chatterbox

Chatterbox is a common English term for a person who talks excessively. It can describe someone who tends to speak at length in social situations, often without giving others a chance to respond. The word is frequently used in a light, humorous, or mildly pejorative way, depending on tone and context. It may be applied to both children and adults, and can be used affectionately among friends.

Etymology and usage: The term blends chatter (to talk rapidly and idly) with box as a playful suffix; it arose in informal English, with first attestations likely in the 19th or 20th century. It is primarily a nickname or descriptive label rather than a formal term.

In common culture and commerce, "Chatterbox" has been adopted as a proper noun for various products, characters, and media properties. It is used for toys or devices that emit sound when activated and for fictional characters who talk a lot. In technology and online communication, the word is sometimes used descriptively to refer to chatty interfaces or chatbots, rather than as a product name.
