What does unclosed mean?
Unclosed means not closed, shut, or sealed. Its clearest use is literal: a door, gate, window, or container that has been left open. It may also describe an issue or process that has not been completed or settled, as in an unclosed question or an investigation that remains unclosed. In everyday speech, open is usually simpler and more frequent, but unclosed can be useful when the emphasis is specifically on the absence of closure rather than on general availability or activity. The word commonly appears in phrases such as “leave the door unclosed,” which describe a condition that is open despite the expectation that it should have been shut. Unclosed is not the same as unlocked: an unlocked object has not been secured with a lock, whereas an unclosed object may never have been shut in the first place. The term is understood in both British and American English and carries no strong regional restriction.

"The gate remained unclosed during the busy afternoon."
"The committee left the question unclosed for further discussion."
One prefix can change the whole picture: add un- to closed, and the door is no longer shut.

Where does unclosed come from?
Unclosed is formed in English by combining the native or Germanic prefix un-, meaning “not,” with the adjective closed. Closed comes through Old French clos from Latin clausus, the past participle of claudere, meaning “to close.” The same Latin root also underlies words such as closure, enclose, and exclude. The prefixed form developed within English to express the opposite condition of being closed.
How unclosed is actually used
The adjective is less common than the neutral word open. It is especially natural in predicative constructions such as “left unclosed” or “remain unclosed,” and can extend figuratively to matters that are unfinished or unresolved.
Easily confused with unclosed
An unclosed door may simply be open, whereas an unlocked door is open because it has not been secured with a lock.
