This book examines the aspect - the relationship between imperfective and perfective verbs - found in the Russian language.

This book was originally published in 1970. Aspect - the relationship between imperfective and perfective verbs - has always been one of the features of Russian grammar that English-speaking students find particularly difficult. It has in fact often appeared to be an insoluble mystery, largely because of the frequency of exceptions to the stated rules. Mr Forsyth suggests that this is the fault of the rules, and that the difficulties in the way of understanding the functioning of aspect stem chiefly from the faulty basis of the traditional definitions. The operation of imperfective and perfective are examined in all forms of the verb including the imperative, infinitive, participles and gerunds, and their usage is amply illustrated by examples from Russian. The aim is to present a total picture of aspect in the Russian language which will be of practical interest to advanced students of Russian, and also contributed to the theoretical study of aspect as a grammatical category.

Joan Bybee and her colleagues present a new theory of the evolution of grammar that links structure and meaning in a way that directly challenges most contemporary versions of generative grammar. This study focuses on the use and meaning of grammatical markers of tense, aspect, and modality and identifies a universal set of grammatical categories. The authors demonstrate that the semantic content of these categories evolves gradually and that this process of evolution is strikingly similar across unrelated languages. Through a survey of seventy-six languages in twenty-five different phyla, the authors show that the same paths of change occur universally and that movement along these paths is in one direction only. This analysis reveals that lexical substance evolves into grammatical substance through various mechanisms of change, such as metaphorical extension and the conventionalization of implicature. Grammaticization is always accompanied by an increase in frequency of the grammatical marker, providing clear evidence that language use is a major factor in the evolution of synchronic language states. The Evolution of Grammar has important implications for the development of language and for the study of cognitive processes in general.

This study presents a semantic framework for analysing all aspectual constructions in terms of the event state distinction, and describes the grammatical expression of aspectual meaning in terms of a theory of grammatical constructions. In this theory, grammatical constructions, like words, are conventionalized form-meaning pairs, which are best described not only with respect to their intrinsic semantic values, but also with respect to the functional oppositions in which they participate.

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.

This book explores the thesis that in the Kwa languages of West Africa, aspect and modality are more central to the grammar of the verb than tense. Where tense marking has emerged it is invariably in the expression of the future, and therefore concerned with the impending actualization or potentiality of an event, hence with modality, rather than the purely temporal sequencing associated with tense. The primary grammatical contrasts are perfective versus imperfective. The main languages discussed are Akan, Dangme, Ewe, Ga and Tuwuli while Nzema-Ahanta, Likpe and Eastern Gbe are also mentioned. Knowledge about these languages has deepened considerably during the past decade or so and ideas about their structure have changed. The volume therefore presents novel analyses of grammatical forms like the so-called S-Aux-O-V-Other or “future” constructions, and provides empirical data for theorizing about aspect and modality. It should be of considerable interest to Africanist linguists, typologists, and creolists interested in substrate issues.
