This book presents a phenomenon-oriented survey of the interaction between phonology and morphology. It examines the ways in which morphology, i.e. word formation, demonstrates sensitivity to phonological information and how phonological patterns can be sensitive to morphology. Chapters focus on morphologically conditioned phonology, process morphology, prosodic templates, reduplication, infixation, phonology-morphology interleaving effects, prosodic-morphological mismatches, ineffability, and other cases of phonology-morphology interaction.
