Sentences may pertain to states or processes or events. They may express duration, frequency, habituality, and many other forms of temporality. How do they do this? It is the aspectual properties of sentences in natural languages which allow the user to express a temporal structure, and Henk Verkuyl presents a unified formal system to account for them. He explains aspectuality in terms of the opposition between terminative aspect and durative aspect, and describes the way in which terminative aspect is compositionally formed on the basis of semantic information expressed by different syntactic elements, in particular the verb and its arguments. The aim is to determine which semantic conditions make a sentence terminative; but at least ten different forms of durative aspectuality are also treated. All are drawn into a theory which can account for both terminative and durative aspectuality together. A Theory of Aspectuality draws together into a coherent whole the author's thinking on the subject over the last twenty years, and will interest all those working on aspect and the semantics of noun phrases. It promises to be a major new contribution to our understanding of the subject.

This book offers both a retrospective view on how theories of aspectuality have developed over the past 30 years, and presents current, new directions of aspectuality research. The articles in this book take a wide crosslinguistic scope including aspectual analyses of the following languages: English and two varieties of English: African American English and Colloquial Singapore English, Italian, French, Bulgarian, Czech, Mandarin Chinese, West-Greenlandic, Wakashan languages, and Nahk-Daghestanian languages.

During the period I have been working on this project I have received institutional support of several kinds, for which I am most grateful. I thank the Institute for Advanced Study at Stanford University, and the Spencer Foundation, for a stimulating environment in which the basic idea of this book was developed. The Max Planck Institute for Psycholinguistics at Nijmegen enabled me to spend several months working on the the manuscript. ANational Science Foundation grant to develop Discourse Representation theory, and a grant from The University Research Institute of the University of Texas, allowed me time to pursue this project. I also thank the Center for Cognitive Science at the University of Texas for research support. I thank Helen Aristar-Dry for reading early drafts of the manuscript, Östen Dahl for penetrating remarks on a preliminary version, and my collaborator Gilbert Rappaport for relentIess comments and questions throughout. The individuals with whom I have worked on particular languages are mentioned in the relevant chapters. I owe a particular debt of gratitude to the members of my graduate seminar on aspect in the spring of 1990: they raised many questions of importance which made a real difference to the working out of the theory. I have benefitted from presenting parts of this material publicly, including cOlloquia at the University of California at Berkeley, the University of California at San Diego, the University of Pennsylvania, Rice University, the University of Texas, and the University of Tel Aviv.

A new contribution to linguistic theory, this book presents a formal framework for the analysis of word structure in human language. It sets forth the network of hypotheses constituting Paradigm Function Morphology, a theory of inflectional form whose central insight is that paradigms play an essential role in the definition of a language's system of word structure. The theory comprises several unprecedented claims, chief among which is the claim that a language's realization rules serve as clauses in the definition of a paradigm function, an overarching construct which is indispensable for capturing certain kinds of generalizations about inflectional form. This book differs from other recent works on the same subject in that it treats inflectional morphology as an autonomous system of principles rather than as a subsystem of syntax or phonology and it draws upon evidence from a diverse range of languages in motivating the proposed conception of word structure.

This synchronic study presents a new onomasiological, frame-theoretical model for the description, classification and theoretical analysis of the cross-linguistic content category aspectuality. It deals specifically with those pieces of information, which, in their interplay, constitute the aspectual value of states of affairs. The focus is on Romance Languages, although the model can be applied just as well to other languages, in that it is underpinned by a principle grounded in a fundamental cognitive ability: the delimitation principle. Unlike traditional approaches, which generally have a semasiological orientation and strictly adhere to a semantic differentiation between grammatical aspect and lexical aspect (Aktionsart), this study makes no such differentiation and understands these as merely different formal realisations of one and the same content category: aspectuality.

This book is a thesis submitted to the Faculty of Arts of the University of Utrecht. It was prepared under the supervision of Prof. Dr. H. Schultink. I would like to express my gratitude to him for his criticisms of earlier versions which led to many improvements, in particular with respect to the exposition of the argument. To my co-referent Dirk van Dalen, reader in the Department of Philo sophy (,Centrale Interfaculteit') of the University of Utrecht, I am greatly indebted for his valuable and fruitful suggestions about problems relevant to both linguistics and logic. Several ideas developed in this study owe their present concrete form to our many discussions. This thesis originates in syntactic research into the Aspects carried out in 1967 under the supervision of Albert Kraak, professor at the University of Nijmegen, who ever since gave much attention to my work in progress. I am very grateful to him for his careful and stimulating criticism as well as for the continuous support he gave me during these years. The present study closely relates to the work of my colleague Wim Klooster with regard to both its theoretical framework and its subject matter. Our joint work on the measurement of duration in Dutch is an integral part of the argument. I have greatly profited from the numerous discussions we have had.
