extro-

Outwards.

An alteration of Latin extra, outside.

This is an invented prefix designed to generate words that are the opposites of those in intro‑. The only common word containing it is extrovert (Latin vertere, to turn) for an outgoing, socially confident person, though the original form extravert is found in psychology. Other examples, such as extrospection, the consideration and observation of things external to the self, are rare.
