Form, function, and frequency in phonological variation

Abstract

AbstractFormal and usage-based approaches to phonology make competing predictions that can be tested with variationist methodology. This paper investigates formal, functional, and frequency effects on (t/d)-deletion in Canadian English. Although initial results suggest a correlation between lexical frequency and deletion, once interaction and lexical effects are taken into account, only phonological and morphological factor groups are significant. Previous reports of frequency effects may result from different measurements of frequency and the contribution of overlapping factor groups. These results suggest that frequency does not operate monotonically but interacts dynamically with the lexicon.
