Ambivert is a noun that refers to someone who has characteristics of an extrovert and an introvert.

The terms introvert and extrovert have been around since roughly the turn of the 20th century. An extrovert is described as someone who enjoys being with other people and an introvert is someone generally prefers to be alone. Our word of the day combines those words to describe someone who has tendencies of both terms.

I had always thought of Donna as an ambivert, but after seeing her warm gregarious social behavior, I see her more as an extrovert. She doesn’t have any introversion in her as far as I can tell.
