Having knowledge of or familiarity with someone or something through experience or introduction.
From Old French acointier, derived from Latin accognitus 'made known'. The word evolved through Anglo-Norman into Middle English, maintaining its sense of becoming familiar with something or someone.
The phrase 'acquainted with' suggests a middle ground of familiarity - more than a stranger but less than a close friend. Interestingly, the word shares its Latin root with 'cognition' and 'recognize', all relating to the process of knowing and awareness!
