lexicalphonology

Lexical Phonology is a theory in linguistics that describes the relationship between the mental lexicon and the phonological component of language. It was first proposed by Morris Halle and Samuel Jay Keyser in the 1970s. The theory posits that the lexicon and phonology are distinct but interconnected components of the language faculty. The lexicon stores the abstract underlying forms of words, while the phonological component is responsible for the surface forms that are actually pronounced.

One of the key principles of Lexical Phonology is the distinction between lexical and post-lexical rules. Lexical rules apply to the underlying forms of words in the lexicon, while post-lexical rules apply to the surface forms after they have been retrieved from the lexicon. This distinction allows for a more nuanced understanding of phonological processes, as it accounts for the fact that some rules apply to individual words, while others apply to larger units of language, such as phrases or sentences.

Another important aspect of Lexical Phonology is the concept of the phonological cycle. This refers to the idea that phonological rules apply in a cyclical manner, with each cycle consisting of a lexical and a post-lexical phase. In the lexical phase, lexical rules apply to the underlying form of a word, while in the post-lexical phase, post-lexical rules apply to the surface form. This cyclical process allows for the generation of complex surface forms from simple underlying forms.

Lexical Phonology has been influential in the development of modern linguistics, as it provides a framework for understanding the relationship between the lexicon and phonology. It has also been applied to a wide range of languages, from English to Japanese, and has contributed to our understanding of the phonological properties of these languages. Despite its successes, Lexical Phonology is not without its critics, and ongoing debates continue to shape the theory and its applications.
