Definitions

Etymology: Petrosis is a modern medical coinage, built on the Greek "petra" meaning "rock" or "stone," with the suffix "-osis" that denotes a diseased or abnormal condition. The word describes the process by which living tissue becomes hard and stony, as in pneumoconiosis-related lung changes or the calcification of organs. The Greek root has a long history in English through words like "petrify," which comes from Latin "petrificare" and entered the language much earlier. Petrosis, by contrast, belongs to the technical vocabulary of medicine, where clinicians formed new terms from classical roots to name specific pathological changes. Its meaning is therefore literal in a way many medical terms are: the tissue turns to something like stone.
