Definition of the word chatter

The word "chatter" has a fascinating etymology. It originated in the 14th century from the Old English word "cattian," which means "to prattle" or "to talk excessively." This Old English word is derived from the Proto-Germanic word "*kattiz," which is also the source of the Modern English word "chat." Over time, the spelling of the word evolved from "chattren" to "chatter," and its meaning expanded to include not just gentle conversation but also empty, disorderly, or excessive talk. Today, "chatter" is often used to describe unnecessary or insignificant conversation, as well as the sound of multiple people talking loudly or unpleasantly.
