This book looks at the various ways in which time is reflected in natural language. All natural languages have developed a rich repetoire of devices to express time, but linguists have tended to concentrate on tense and aspect, rather than discourse principles. Klein considers the four main ways in which language expresses time - the verbal categories of tense and aspect; inherent lexical features of the verb; and various types of temporal adverbs. Klein looks at the interaction of these four devices and suggests new or partly new treatments of these devices to express temporality. Klein is also author of "Parsing" (Athenaum, 1991); "Einfuhrung in die Computerlinguistik" (Kohlhammer, 1974); "Variation in der Sprache" (Scriptor, 1974); "Developing Grammars" (Springer Verlag, 1979); "Speech, Place and Action" (Wiley, 1982); "Second Language Acquisition" (CUP, 1986); "Utterance Structure" (J. Benjamins, 1992); and articles in "Language", "Linguistics", "Linguistische Berichte", "Zeitschrift fuer Literaturwissenschaft und Linguistik", and "Studies in Second Language Acquisition". He is editor-in-chief of "Linguistics", and co-editor of "Zeitschrift fuer Literaturwissenschaft und Linguistik".
