applyable

Applyable is an adjective used to describe something that can be applied or is relevant to a given situation. In standard modern English, the preferred spelling is “applicable.” The form “applyable” is a nonstandard or infrequently used variant that appears in some texts, particularly older material or informal writing.

Usage: When addressing whether a rule, method, or principle applies to a case, “applicable” is the usual choice. “Applyable” may be encountered but is generally avoided in formal writing; some editors treat it as a misspelling of “applicable.” The noun form “applicability” and the adverb “applicably” derive from the standard form.

Origin and related terms: The word derives from the verb “apply” with the suffix -able, and is closely related to “applicable” (having practical relevance or suitability). “Applicability” refers to the quality of being able to be applied in a given context. In programming or law, precise vocabulary tends to favor “applicable” for clarity.

Examples: It is applicable to this case. The regulation is applicable to all vehicles. The use of “applyable” is rare and often discouraged in formal documents. See also applicable, applicability, applicability (noun form), and related terms discussing relevance and usability.
