Etymology: "Spondylo-" comes from Greek "spondylos," meaning "vertebra" or "joint of the spine." In Homer's time the word could also refer to a whorl or the stem-joint of a plant, and the same sense of a jointed, ringed structure carried over when anatomists needed a term for the backbone's segments. Latin borrowed the Greek word as "spondylus," which in Latin texts was used for vertebrae as well as for a type of shellfish whose shell has ridged, jointed edges. English did not inherit "spondylo-" from ancient medicine. It is a modern combining form, built in the 18th and 19th centuries by physicians and scientists who drew on Greek roots to name disorders and structures of the spine, such as "spondylitis" (inflammation of the vertebrae) and "spondylosis" (degeneration of the spinal joints). Because these terms were coined in modern clinical Latin and Greek, the prefix is a scientific formation rather than a word that ancient physicians used in the same way.
