labellable

Labellable is an adjective meaning capable of being labeled or assigned a label. It describes items, data, or concepts that can bear a label for identification, classification, or categorization. The form is built from the noun label plus the suffix -able and is used to express potential labeling rather than the act of labeling itself.

Spelling variants include labellable and labelable, with some variation between British and American English. The double-l and the choice of suffix reflect considerations of readability and etymology, but both forms convey the same general idea of assignable labels.

Common contexts for the term include data science and information management, where labellable data refers to data points that have or can be given ground-truth labels for supervised learning. In cataloging, biology, and taxonomy, labellable items are those capable of receiving identifying tags or labels for reference. The term is often contrasted with unlabeled data or unlabeled specimens, emphasizing the potential to assign a meaningful label in a labeling workflow.

Usage tends to appear in technical or formal writing rather than everyday language. The related concepts include labeling, label, labelled, and labeling schemes, all of which concern how items are identified, categorized, or annotated with textual markers.
