calculous positive

Morphology

calculous = calculus (semi-transparent) = calculus + ous

Formed by adding the adjectival suffix '-ous' to 'calculus'; the medical sense 'stone' is specialized and may be confused with the mathematical sense, so the relation is not fully obvious to learners.

Etymology

Calculous comes from the Latin calculus, which means 'small stone' and gave us calculate and calculus because people once used pebbles to count. So calculous means 'caused by' or 'full of' small stones in the body, like kidney or gall stones.
