unmarked

Something is "unmarked" when it has no visible sign, label, name, or other identifying feature. Picture fresh snow before anyone has walked across it: smooth, clear, and still untouched. The word is often used for real things, such as an unmarked envelope, an unmarked police car, or an unmarked path with no sign to guide you. It can also describe places that have not been clearly shown or named on a map. Often, the idea is that some mark would normally be there, but it is missing.

"Unmarked" usually means that something has no mark, sign, label, or clear feature that would identify it. It is often used when we expect some kind of marking but do not see one. An unmarked envelope has no writing or return address. An unmarked police car does not have the usual police signs on the outside. An unmarked road or path has no sign to show where it leads.

The word can also be used for places or objects that are plain because nothing has been added to them yet. Fresh snow can be called unmarked when no footprints or tracks have touched it. A page can be unmarked if nothing has been written on it. In these cases, the word suggests a clean surface that is still untouched.

Sometimes the word carries a more serious feeling. An unmarked grave has no stone or sign to show who is buried there. An unmarked crossing can be dangerous because there is no warning sign. The word may also be used in a wider, more figurative way, as in a face unmarked by worry or age, meaning no visible sign of those things can be seen. In all of these uses, the central idea stays the same: something that would show, name, or identify is absent.
