Tantamount comes from the Anglo-French phrase tant amunter, meaning "to amount to as much." This phrase comes from the Old French tant, meaning "so much" or "as much," and amounter, meaning "to ascend" or "to add up to." When tantamount first entered English, it was used similarly to the Anglo-French phrase, as a verb meaning "to be equivalent." "His not denying tant-amounteth to the affirming of the matter," wrote clergyman Thomas Fuller in 1659, for example. There was also a noun tantamount in the 17th century, but the adjective is the only commonly used form of the term nowadays.
