Complex predicates can be defined as predicates that are composed of more than one grammatical element (either morphemes or words), each of which contributes a nontrivial part of the information of the complex predicate. The papers collected in this volume represent a variety of approaches to the question of the range and nature of complex predicates, and draw on data from a wide spectrum of languages. This collection develops a better understanding of the range of phenomena that a general theory of complex predicates would have to account for, and to see what kinds of linguistic ideas and methodologies would be necessary for such a task.
