Notusable

Notusable is an English adjective used to describe something that cannot be used. The term is frequently encountered in technical contexts as a label or status indicator. In written form it may appear as two words (not usable), as a hyphenated form (not-usable), or as a single compound word (notusable) in programming identifiers or file names.

In software and information technology, notusable is used to mark features, inputs, or data that are currently unusable due to errors, missing dependencies, licensing restrictions, or incomplete implementation. It can appear in issue trackers, release notes, user interfaces showing disabled controls, or data validation schemas to indicate items that should be ignored.

In manufacturing and logistics, not usable describes parts, tools, or shipments that fail quality control or do not meet specifications and thus cannot be employed in production.

In data management and annotation, not usable labels may mark data points that are corrupted, missing critical fields, or restricted by privacy or security constraints, excluding them from analysis.

As a term, notusable is not a standard dictionary entry; its use is largely pragmatic and context dependent. It sometimes functions as a code name, tag, or identifier in software and records, where unambiguous machine readability favors a single token without spaces.
