Etymology: Medicine built "denervated" from parts that were already English. The prefix "de-" means "removing" or "reversing", and "nerve" comes from Latin "nervus", which meant sinew or tendon before it came to mean the fibres that carry signals in the body. The suffix "-ate" turns the noun into a verb, so "denervate" means to cut off a nerve supply, and "denervated" describes tissue in that state. The word is a modern technical coinage built from these classical parts, not a term that ancient physicians used. Because "nerve" carried the older sense of a tendon for centuries, the word's root once described something quite different from the nervous system that the term now names.
