According to Cowan, an underground rule is one that affects underlying but not surface structure of the item responsible for a phonological change. (DD)

Addresses the relationship between phonology and morphology, using the vowel alternations of Standard German Umlaut and Ablaut as relevant examples. The article analyzes Umlaut as a completely unified process of vowel fronting, whereas it argues that Ablaut is synchronically a totally unpredictable vowel change found in the paradigms of strong…

Revised version of a paper published in the "Edinburgh Working Papers in Linguistics," n1. (DD)

Shows that the Scottish Vowel Length Rule supports Kiparsky's (1988) association of diffusing sound changes with lexical, and neogrammarian changes with postlexical rules, and to some extent, is a clearer illustration of Harris' (1989a: 55) notion of a phonological "life cycle" of changes and rules.

Presents: (1) the basic facts of vowel-zero alternations and palatalization in Polish; (2) a nonlinear account of the vowel-zero alternations; (3) a reanalysis of palatalization facts in terms of morpholexical rules; and (4) speculations relating to learnability considerations and the nature of linguistic theory construction.

Presents an analysis of colloquial-spoken Thai, showing how different tempi can be interrelated. Analysis of language processes, deletion paths, and syllable structure leads to the conclusion that phonological processes found synchronically in related but different rates of delivery should be captured by a universally applicable rule with certain…
