Answer:
True. A complete set of rules that generate or produce all acceptable utterances and not ill-formed ones is called grammar. A grammar is a system of rules that governs the production of language, including rules for syntax, morphology, phonology, and semantics. A grammar can be used to generate or analyze sentences, and it provides a framework for understanding how language is structured and how it can be used to convey meaning. Grammars can be formal or informal, and they can be descriptive or prescriptive in nature, depending on their purpose and scope.
