relevance by virtue of being applicable to the matter at hand
"The applicability of this new law immediately became clear as it addressed every detail of our current dispute."
The degree to which a thing is applicable; relevancy.
"The applicability of these new safety regulations varies significantly depending on the size of each factory."
In plain English: Applicability is how well something fits or works for a specific situation.
"The applicability of this new rule affects many small businesses across the country."
Usage: Use this formal term when discussing how well a rule, theory, or solution fits a specific situation rather than simply saying something is "relevant." Avoid using it in casual conversation where simpler words like "suitability" would be more natural.
