Optionality, lexicality and sound change
Published online by Cambridge University Press: 01 March 1997
Abstract
This paper investigates the relationship between variability and lexicality on the one hand and sound change on the other within the theory of Lexical Phonology. The former leads to the proposal of the Optionality Constraint (OC), which prohibits the application of optional rules in the lexical module. The constraint is found to be violated at the word level. The violation of OC as well as of other lexical modular principles is accounted for by the help of a new licensing principle, called the Polarity Principle. This allows for interacting modules to have different properties of representation and rule application at their opposite ends. The OC leads to a resolution of the Neogrammarian Controversy, that is consonant with the standard assumption concerning sound change, namely, the inherent relation between the latter and variability.
