Part of speech: adjective

Definitions

Etymology: "Unlined" is simply "lined" with the negating prefix "un-" attached, and the two parts have long histories of their own. The prefix goes back through Old English "un-" to a Proto-Germanic root shared with German "un-" and Dutch "on-", and it has been attached to adjectives in English for well over a thousand years. "Lined" comes from "line" in its sense of a layer or lining sewn inside a garment, a use that developed from the older idea of a thread or cord. The result is a plain descriptive coinage: a garment, curtain or coat with no inner layer of fabric. Its meaning is fixed by the two parts, so the interest lies mainly in the prefix, which can be attached to almost any adjective to create a ready-made opposite.
