Generative grammar predicts grammatically correct sentences using a set of rules. Noam Chomsky’s work contributed to the cognitive revolution in psychology and developed the theory of universal grammar. Syntax, semantics, phonology, and morphology are studied, with derivation trees being a primary focus. Generative grammar formalizes implicit language rules and is used in music studies.
Generative grammar is a branch of theoretical linguistics that works to provide a set of rules that can accurately predict which combinations of words are capable of creating grammatically correct sentences. Those who study this topic hope to improve our general understanding of the mental structure of the human species as a whole. Generative grammar has been associated with several schools of linguistics, including transformational grammar, relational grammar, categorical grammar, tree grammar, head-driven sentence structure grammar, generalized sentence structure grammar, relational grammar, and lexical-functional grammar .
The study of generative grammar began in the 1950s as a result of the work done by Noam Chomsky, a notable American linguist, philosopher, writer, and lecturer. He took a naturalistic approach to the study of language that is said to have contributed to the cognitive revolution in psychology. A key component of his work has been the theory that the properties of generative grammar derive from a universal grammar common to all spoken and written linguistic forms. Chomsky’s hierarchy is a tool he developed to help compare the properties of various grammatical systems and their growing expressive capabilities.
The primary components studied by generative grammar experts include syntax (structure of sentences), semantics (linguistic meaning), phonology (sound patterns of language), and morphology (structure and meaning of words). Derivation trees are a primary focus of study for many linguists working in this field; these diagrams view a sentence as a tree with connected subordinate and superordinate branches as opposed to a simple string of words.
Generative grammar can be thought of as a way of formalizing the implicit rules that a person seems to know when speaking in his native language. Theories are based on the belief that humans have an innate linguistic faculty that allows children to learn to speak their native language in little to no time with minimal conscious effort. The rules established by this branch of theoretical linguistics can be considered a type of algorithm designed to predict grammaticality with a “yes” or “no” outcome.
While generative grammar may initially appear to have very limited practical applications outside linguistic studies, it is interesting to note that the ideas behind this particular branch of theoretical linguistics have also been used to advance the study of music. Schenkerian analysis helps define tonality in music by applying generative principles, and famed composer Fred Lerdahl has also used them to advance his musical studies.
