Predicting distributional restrictions on prenasalized stops

Abstract

Previous studies on prenasalized stops (NCs) focus mainly on issues of derivation and classification, but little is known about their distributional properties. The current study fills this gap. I present results of a survey documenting positional restrictions on NCs, and show that there are predictable and systematic constraints on their distribution. The major finding is that NCs are optimally licensed in contexts where they are perceptually distinct from plain oral and nasal stops. I provide an analysis referencing auditory factors, and show that a perceptual account explains all attested patterns.
