Etymology: "Monoplegic" is an adjective, and also a noun, for a person affected by paralysis of a single limb. It is built from "monoplegia" plus the adjective-forming suffix "-ic", so the real interest lies in the parts. The first part, "mono-", comes from Greek "monos", meaning "single" or "alone", which is also behind "monologue" and "monarch". The second part comes from Greek "plēgē", meaning "stroke" or "blow", a root that gives English "apoplexy" and "paralysis" through the sense of being struck down. Put together, "monoplegia" literally means a single striking-down, a stroke affecting one limb. Medical writers formed the term from these Greek elements, so the word is a modern scientific coinage rather than something ancient physicians used, even though its building blocks are classical. The adjective then follows the usual pattern of medical vocabulary, where "-ic" turns a condition into a description of the patient or symptom.
