- diamond:  Diamond is an alteration of adamant, a rather archaic term which nowadays refers to hard substances in general, but formerly was also used specifically for ‘diamond’. The alteration appears to have come about in Latin of post-classical times: adamant- (stem of Latin adamas) evidently became Vulgar Latin *adimant- (source of French aimant ‘magnet’), which appears to have opened the way to confusion, or at least association, with words beginning dia-. The result was medieval Latin diamant-, which passed into English via Old French diamant.
