One of the most striking trends across linguistic research in recent years has been the examination of the interfaces between the various subcomponents of the language faculty. Yet, approaches to these interfaces across different theoretical frameworks differ substantially. This volume pulls together research into Morphology and its interfaces from researchers employing a variety of different theoretical and methodological perspectives: Morphology is a diverse field, and rather than aiming to collect works sharing a particular approach or framework of assumptions, this collection instead captures the diversity and provides an overview of the state of the research field while also addressing particular empirical phenomena with up-to-date analyses. The articles collected provide case studies from a diverse variety of languages revealing properties of the interfaces that morphology shares with syntax, semantics, phonology, and the lexicon, while the volume's inclusive cross-theoretical approach will serve to introduce readers to the findings of alternative frameworks and methodologies.
