"The Phonology of Liquids" is an investigation into the nature of liquid consonants. This dissertation principally addresses questions of the featural content of liquids along with the hierarchical relations among those features. A major finding of this study is that both the class of rhotics and the class of liquids (defined as rhotics and sonorant laterals) are phonological valid classes. While traditional analyses have used manner features to distinguish among liquid consonants, Walsh Dickey demonstrates that rhotics and laterals are instead defined and differentiated by complexes of Coronal and Dorsal place features.
