adverb词源
Old English (as a noun)， from Old French adamaunt-, via Latin from Greek adamas, adamant-, 'untameable， invincible' （later used to denote the hardest metal or stone， hence diamond）， from a- 'not' + daman 'to tame'. The phrase to be adamant dates from the 1930s， although adjectival use had been implied in such collocations as 'an adamant heart' since the 16th cent.
