the.com/extroversion

means A personality tendency toward drawing energy from outward engagement — social interaction, stimulation, and the external world — rather than from solitude.

from Built from Latin extra/extro- ('outward, beyond') plus vertere ('to turn') — literally 'turning outward.' The psychological sense was shaped in the early 20th century, notably by Carl Jung, who paired it with its opposite, introversion, to describe where a person's energy and attention naturally flow — out toward others, or inward toward the self. The spelling 'extra-' is technically more correct by the Latin, but 'extro-' caught on to mirror 'introversion' and stuck.
