Phi-features, such as person, number, and gender, present a rare
opportunity for syntacticians, morphologists and semanticists to
collaborate on a research enterprise in which they all have an equal stake
and which they all approach with data and insights from their own fields.
This volume is the first to attempt to bring together these different
strands and styles of research. It presents the core questions, major
results, and new directions of this emergent area of linguistic theory and
shows how Phi-Theory casts light on the nature of interfaces and the
structure of the grammar. The book will interest scholars and students of
all aspects of linguistic theory at graduate level and above.
