Etymology

The word tantamount emerged in the early 17th century, blending the French-derived tant (implying equality) with amount (suggesting measurable value). Originally used in diplomatic contexts to denote "equivalent in weight or importance," it later broadened to abstract equivalence. The logic mirrors balancing scales—tant and amount together imply "equal measure."
