Etymology: The Greek word "apophysis" was built from two parts: "apo", meaning "away from" or "off", and "phuein", "to bring forth" or "to grow". Together they described something that grows out from a body, an offshoot. Greek writers used it for things that sprouted or projected from a larger structure, and the same sense carried into scientific Latin and then English. The prefix and root are ancient, but the English term is a technical borrowing. Its appeal lies in how little the modern meaning has drifted from the original image. A bone spur, a process on a vertebra, or a branching growth on a plant or insect is still, literally, something that grows off the main body. The word stayed close to its physical picture while becoming a precise term for anatomy and botany.

Synonyms: outgrowth, projection, appendage, protrusion, extension
