Unlabeled

Describing something that lacks a label, tag, or other form of identification. This could apply to containers, products, documents, or any item without a clear indication of its contents, origin, or purpose. The absence of labeling can lead to ambiguity, confusion, or potential misuse, as the intended information is not readily available. It often necessitates further investigation or inference to determine the characteristics of the unlabeled object. The term also extends to data or categories that have not been explicitly classified.
