Welcome to the Department of Linguistics.

Linguistics is the scientific study of human language, from the sounds and gestures of speech up to the organization of words, sentences, and meaning. Linguistics is also concerned with the relationship between language and cognition, society, and history.

The Department of Linguistics at the University of Pennsylvania is the oldest modern linguistics department in the United States, founded by Zellig Harris in 1947. The department is known for its interdisciplinary research, spanning many subfields of linguistics, as well as integration of theory, corpus research, field work, and cognitive and computer science.

The department has both a graduate Ph.D. program and undergraduate major and minors. For the specializations of our faculty, please see the research section.

This volume brings together some of the most recent developments in the field of experimental pragmatics, specifically empirical approaches to theoretical issues in presupposition theory. It includes studies of the online processing of presupposed content; investigations of the interpretive properties of presuppositions in various linguistic contexts; comparative perspectives relative to other aspects of meaning, such as asserted content and implicatures; cross-linguistic comparisons of presupposition triggers; and perspectives from language acquisition. Taken together, these novel contributions provide a snapshot of state-of-the art developments in this area and will serve as a point of reference for numerous emerging avenues of future work. It makes for an ideal set of readings for advanced university courses on experimental studies of meaning and is a must-read for anyone interested in experimental research on meaning in natural language.

In this book Robin Clark explains in an accessible manner the usefulness of game theory in thinking about a wide range of issues in linguistics. Clark argues that we use grammar strategically to signal our intended meanings: our choices as speaker are conditioned by what choices the hearer will make interpreting what we say. Game theory — according to which the outcome of a decision depends on the choices of others — provides a formal system that allows us to develop theories about the kind of decision making that is crucial to understanding linguistic behavior. Clark argues the only way to understand meaning is to grapple with its social nature: that it is the social that gives content to our mental lives. The resulting theory of use will allow us to account for many aspects of linguistic meaning, and the grammar itself can be simplified. The book includes an extended argument in favor of the social basis of meaning; a brief introduction to game theory, with a focus on coordination games and cooperation; discussions of common knowledge and games of partial information; models of games for pronouns and politeness; and the development of a system of social coordination of reference.

The Atlas of North American English provides the first overall view of the pronunciation and vowel systems of the dialects of the U.S. and Canada. The Atlas re-defines the regional dialects of American English on the basis of sound changes active in the 1990s and draws new boundaries reflecting those changes. It is based on a telephone survey of 762 local speakers, representing all the urbanized areas of North America.

Drawing on cutting-edge developments in biology, neurology, psychology, and linguistics, Charles Yang's The Infinite Gift takes us inside the astonishingly complex but largely subconscious process by which children learn to talk and to understand the spoken word. Yang also puts forth an exciting new theory that we learn our native languages in part by unlearning the grammars of all the rest.

Bringing the advances of theoretical linguistics to the study of language change in a systematic way, this innovative textbook shows that theoretical linguistics can be used to solve problems where traditional approaches to historical linguistics have failed to produce satisfying results, and that the results of historical research can have an impact on theory. The book first explains the nature of human language and the sources of language change in broad terms. It then focuses on different types of language change from contemporary viewpoints, before exploring comparative reconstruction — the most spectacular success of traditional historical linguistics — and the problems inherent in trying to devise new methods for linguistic comparison. Positioned at the cutting edge of the field, the book argues that this approach can and should lead to the re-integration of historical linguistics as one of the core areas in the study of language.

This book is the first detailed examination of morphology and phonology from a phase-cyclic point of view (that is, one that takes into account recent developments in Distributed Morphology and the Minimalist program) and the only recent detailed treatment of allomorphy, a phenomenon that is central to understanding how the grammar of human language works. In addition to making new theoretical proposals about morphology and phonology in terms of a cyclic theory, Embick addresses a schism in the field between phonological theories such as Optimality Theory and other (mostly syntactic) theories such as those associated with the Minimalist program. He presents sustained empirical arguments that the Localist view of grammar associated with the Minimalist program (and Distributed Morphology in particular) is correct, and that the Globalism espoused by many forms of Optimality Theory is incorrect.
