Generation grammar
Generative grammar or variant creation grammar is one of the many theories of syntax. This is the application of the proof theory approach to syntactic research, which was initiated by Noam Chomsky and influenced by formal grammar theory. Generation grammars are a set of rules that constantly "generate" pre-made expressions of natural language. The creation grammar was invented by Noam Chomsky in the late 1950s. In the early days, this theory was called the variant grammar, and it is still commonly referred to as the variant grammar, as far as Chomsky's theory is concerned. The name of the present generation grammar is used as a generic term for several conflicting doctrines. Chomsky's current doctrine is called minimalism. In addition, it is the main doctrine of creation grammar, which is often referred to, such as nuclear core structure grammar, vocabulary function grammar, category grammar, relational grammar, connection grammar, and suffix grammar. Chomsky argues that the major components of creation grammars are components of "immanent" universal grammars.
