Nondescript means so ordinary and unremarkable that it's hard to describe or remember. When something is nondescript, it has no interesting or distinctive features that make it stand out.

A nondescript building might be plain gray concrete with no decoration or character, the kind of building you could walk past every day and never really notice. A nondescript car could be an average-sized sedan in beige or gray, nothing flashy or memorable about it. When a witness tells police the suspect wore “nondescript clothing,” they mean ordinary clothes that could belong to almost anyone: plain jeans, a basic T-shirt, nothing special.

Writers sometimes use nondescript intentionally. A spy story might describe an agent as deliberately nondescript, dressed to blend into a crowd without attracting attention. In daily life, though, calling something nondescript usually means it lacks personality or charm. A nondescript restaurant might serve okay food but have nothing that makes you want to return. A nondescript room might be clean and functional but completely forgettable, with blank walls and generic furniture that could fit almost anywhere.
