Etymology: Dysesthesia is built from two Greek elements. The prefix "dys-" means "bad," "difficult," or "abnormal," and it appears in many medical terms such as "dyspepsia" (poor digestion). The second element comes from "aisthēsis," the Greek word for perception or sensation, which gave English "anaesthesia" (loss of sensation) and "aesthetics" (the study of what is perceived as beautiful). Joined together, the two parts describe sensation that has gone wrong. The result is a term for a disordered sense of touch, in which ordinary contact such as clothing brushing the skin or a light breeze can register as burning, stinging, or aching. The word's pattern is typical of medical vocabulary: the Greek roots are combined in a precise way to name a specific condition, so the meaning can be read straight from its parts.
