This textbook provides a thorough and comprehensive introduction to modern binding theory, introducing a huge variety of nominal and especially pronominal expressions from the world's languages. Written in a clear and accessible style, and with numerous exercises and examples, this textbook will be invaluable to graduate and advanced undergraduate students of syntax and semantics.
