Etymology: Amyosthenia is a modern medical coinage built entirely from ancient Greek parts. The prefix "a-" means "not," "myo-" comes from "mys," meaning muscle, and "sthenos" means strength, while the suffix "-ia" marks a condition or disease. Put together, the name describes a state of muscles lacking their usual strength, and it reads like a clinical label that a physician might have devised to name a newly recognised pattern of weakness. Because the word is a scientific construction, it did not exist in classical Greek, where no one spoke of a "lack of muscle strength" under this name. Its value lies in its transparency: a reader who knows the component parts can work out the meaning without a dictionary. Many medical terms follow this same pattern, combining Greek elements into a precise descriptor.
