Abstract

Alveolar stops, the most unmarked consonants in English, are prone to several consonantal lenitions. This paper investigates patterns of alveolar stop variation over a word boundary when an alveolar stop precedes a nasal or a sequence of an unstressed vowel and a nasal. Results indicate that a word-final alveolar stop was subject to glottal replacement, losing its place features, and such a glottal was released nasally. The underlying voicing contrast played a crucial role to the alternations in which voiceless alveolar stops often underwent glottaling whereas voiced counterparts often participated in flapping. When the following segment is a vowel, and thus an alveolar stop was flanked by weak segments, an alveolar stop was frequently weakened while when the following segment is a nasal, an alveolar stop rarely participated in such a process and was realized as a stop.
