masc nom sg of adhippayāsa (noun)
Analysis. adhi- (on top of) + ppayāsa (effort, exertion); literally 'effort laid on top', hence distinction or differentiation as that which stands out or is marked by extra effort or emphasis.
Etymology. The prefix adhi- (on top of, presiding over) combines with payāsa (exertion, effort), from √paya (to toil, strain). The sense shifts from literal 'effort imposed above' to 'that which makes a difference' or 'what distinguishes one thing from another', the mark of distinction being what stands out or is emphasized.
