six-figure

The compound adjective "six-figure" is a modern financial term built transparently from its two constituent English words. "Six," a cardinal number with ancient Indo-European roots, specifies the quantity of numerical digits. "Figure," derived from Latin figūra meaning "shape" or "form," evolved to denote a numerical digit or symbol. The logic of the compound is purely arithmetic: a number containing six digits (100,000 to 999,999). It emerged in the 20th century as a concise descriptor for high earnings, leveraging the immediate comprehensibility of its components to denote a specific, prestigious income bracket.
