noun a clavier with strings that are plucked by plectra mounted on pivots
originEarly 1600s, borrowed from French harpechord (“harp string”), from New Latin harpichordium, from harpa (“harp”) + chorda (“string”). Influenced by and possibly also borrowed from Italian arpicordo, producing variant spellings. The unetymological -s-, which predominates by the 1660s, is of unclear origin.
