The grammatical category in English grammar that expresses count distinctions is referred to as number. The number denotes whether we are speaking of a single item (plural) or multiple items (singular). Comprehending the notion of number is crucial for accurately structuring sentences and guaranteeing congruence among subjects, verbs, and other constituents of discourse. This is a summary of how numbers function in English grammar.
