Etymology: The word descends from Latin "urtica," the nettle, a plant named for the burning sting of its hairs. That name comes from "urere," "to burn," so the nettle was literally the burning plant. Latin speakers made "urticare," "to sting or itch like a nettle," from the same root, and English drew on that verb family for its vocabulary of skin irritation. The word itself is a learned formation, built on the Latin verb with the suffix "-ant," which names an agent that performs an action. It is a technical coinage, not an old folk word, and its exact first English appearance is uncertain. Its close relative "urticaria," the medical term for hives, follows the same nettle-derived path.
