'extrovert' originates from Latin, specifically the elements 'extra' meaning 'outside' and 'vertere' meaning 'to turn'.

'extrovert' was formed in English (and earlier spelled 'extravert') in the early 20th century, influenced by Latin components and psychological usage (contrast with 'introvert'), and eventually became the modern English word 'extrovert'.

Initially used in psychological contexts to mean 'turned outward' (i.e., focused on the external world); over time it came to refer specifically to an outgoing, socially confident person.
