Abstract

Phonology is the study of abstract sound patterns in human language, as opposed to phonetics, which studies all aspects of speech, including articulation and acoustics. The phonology of each language consists of various computations. In Sound Pattern of English (SPE) the computations are called rules, and the phonology of a language is a complex function resulting from composing the rules in a particular order. Aside from internalism, naturalism and nativism are the most important notions of Chomsky's legacy in linguistics. SPE phonology explicitly adopts strict and consistent naturalism, internalism and nativism. The rightful legacy of SPE includes the naturalism, internalism and nativism found also in Chomsky's syntactic work. The SPE arguments given against building markedness into the formal theory are consistent with the idea of phonology as naturalistic inquiry, and these convincing arguments are only reinforced by the inconsistencies in markedness‐based approaches.
