conversant
UK: kənˈvɜːsənt | US: kənˈvɜːrsənt
adj. familiar or knowledgeable about a subject through study or experience
adj. able to hold a conversation in a foreign language
The word "conversant" originates from Latin conversari (to associate with, dwell), derived from con- (together) + versare (to turn frequently). The root vers reflects the idea of "turning" or "engaging," metaphorically extending to social interaction or familiarity. Over time, it evolved in Old French as converser (to live among, converse) before entering Middle English with its current meaning of being knowledgeable or fluent.
