IPA: /ˌæm.bɪˈvɜːr.ʒən/
KK: /æmˈbɪvɜrʒən/
A personality trait that combines characteristics of both being reserved and outgoing, allowing a person to adapt their behavior depending on the situation.
Her ambiversion allows her to enjoy both social gatherings and quiet time alone.
Ambiversion is formed from "ambi-" (meaning both) and "versio" (from Latin "vertere", meaning to turn). The word describes a personality type that exhibits qualities of both introversion and extroversion, thus 'turning' towards both sides.
Think of 'ambi-' meaning both, and 'versio' relating to turning — this helps you remember that ambiversion refers to a personality that can turn towards both introverted and extroverted traits.
