Etymology: Quadriparesis is a compound built from two classical parts. The first, "quadri-", comes from the Latin "quadri-", a combining form of "quattuor", meaning "four", so the word literally means four-sided weakness. The second part, "paresis", comes from Greek "paresis", meaning "letting go" or "relaxation", from "parienai" (to let go, to send forth), and in medicine it denotes partial paralysis, a weakening of muscle power rather than total loss of movement. Put together, the word describes weakness affecting all four limbs at once. The "quadri-" element is the same one found in words like "quadrilateral" and "quadruplet", which makes the term easy to decode once you know the prefix and the medical sense of "paresis". Because it is built from Greek and Latin parts, it is a technical coinage of modern medicine rather than an ancient term; the Greek and Latin elements were assembled into a clinical label to describe a specific clinical pattern.
