The act or habit of chattering; continuous idle talk or the sound of repeated clicking or rattling.
From chatter (Middle English from Old Norse origin meaning to make rapid sounds) + -ation (Latin suffix forming nouns of action). The term evolved to describe both the sound itself and the behavior of talking excessively.
Chatteration captures something fascinating: it's one of the few English words that describes both a physical sound and a social behavior, which is why you might hear 'the chatteration of teeth' during winter and 'the chatteration of gossip' at lunch time.
