Tantamount → It is formed from 'tant' (from Latin 'tantus', meaning so much or so great) and 'amount' (from Old French 'amont', meaning to rise or to ascend). The word 'tantamount' means equivalent in value, significance, or effect, suggesting that one thing is as great as another.
Think of 'tant' meaning 'so much' and 'amount' meaning 'to rise' — together they suggest that one thing rises to the same level as another, helping you remember that 'tantamount' means equivalent.
