tant-

1. Equivalent, as in value, force, effect, or signification: "His angry speech was tantamount to his resignation as CEO of the company."
2. If something is tantamount to something else, it is the same or equal to it: "The man's silence was tantamount to an admission that he stole the purse."
3. Equivalent to a particular thing in effect, outcome, or value, especially something unpleasant: "She responded with an answer that was tantamount to a refusal."
4. Etymology: From about 1641, from the verbal phrase tant amount, "be equivalent" (1628), from Anglo-French tant amunter, "amount to as much" (1292), from Old French tant, "as much" (from Latin tantus, from tam, "so") plus amonter, "amount to, go up" ("to the mountain", from Latin ad-, "to" + montem, "mountain").

So much has been entrusted to us.
