Generative grammar is a theoretical approach in linguistics that regards grammar as a domain-specific system of rules that generates all and only the grammatical sentences of a given language. In light of poverty of the stimulus arguments, grammar is regarded as being partly innate, the innate portion of the system being referred to as universal grammar. The generative approach has focused on the study of syntax while addressing other aspects of language including semantics, morphology, phonology, and psycholinguistics.

In linguistics, a grammar is the set of rules for how a natural language is structured, as demonstrated by its speakers or writers. Grammar rules may concern the use of clauses, phrases, and words. The term may also refer to the study of such rules, a subject that includes phonology, morphology, and syntax, together with phonetics, semantics, and pragmatics. There are, broadly speaking, two different ways to study grammar: traditional grammar and theoretical grammar.
A generative parse tree: the sentence is divided into a noun phrase (subject), and a verb phrase which includes the object. This is in contrast to structural and functional grammar which consider the subject and object as equal constituents.
