c.1300, “state of being acquainted;” late 14c., “person with whom one is acquainted;” also “personal knowledge;” from Old French acointance “acquaintance, friendship, familiarity,” noun of action from acointer (see acquaint). Acquaintant (17c.), would have been better in the “person known” sense but is now obsolete.
see nodding acquaintance; scrape up an acquaintance.
