Nonapplicable

Nonapplicable is an adjective used to indicate that something does not apply to a given situation, condition, or item. It is commonly found in forms, checklists, manuals, and legal or technical documents to mark irrelevance or inapplicability.

Etymology and forms: The term is formed from the negating prefix non- with applicable, itself derived from Latin applicabilis meaning able to be applied. In practice, writers may encounter hyphenated forms such as non-applicable or, more often in modern prose, the closed form nonapplicable.

Variants and usage: In everyday writing, not applicable is usually preferred for readability. In data entry, software interfaces, and standardized forms, nonapplicable or N/A may appear as a deliberate field value indicating that a question or rule does not pertain to the subject.

Style and considerations: Some style guides treat nonapplicable as nonstandard or overly technical, recommending the two-word construction or the abbreviation N/A. When clarity is needed, particularly outside technical contexts, not applicable is recommended.

Applications and examples: This field is nonapplicable to the required test results. The clause is not applicable in this jurisdiction. The rule is not applicable to exemptions. In data schemas, a nonapplicable flag can denote that the attribute does not apply.
