**The DVD content is now available online and can be accessed at the Gallaudet University Press website. Completely reorganized to reflect the growing intricacy of the study of ASL linguistics, the 5th edition presents 26 units in seven parts. Part One: Introduction presents a revision of Defining Language and an entirely new unit, Defining Linguistics. Part Two: Phonology has been completely updated with new terminology and examples. The third part, Morphology, features units on building new signs, deriving nouns from verbs, compounds, fingerspelling, and numeral incorporation. Part Four: Syntax includes units on basic sentence types, lexical categories, word order, time and aspect, verbs, and the function of space. The fifth part, Semantics, offers updates on the meanings of individual signs and sentences. Part Six: Language in Use showcases an entirely new section on Black ASL in the unit on Variation and Historical Change. The units on bilingualism and language and ASL discourse have been thoroughly revised and updated, and the Language as Art unit has been enhanced with a new section on ASL in film. Two new readings update Part Seven, and all text illustrations have been replaced by video stills from the expanded DVD. Also, signs described only with written explanations in past editions now have both photographic samples in the text and full demonstrations in the DVD.

The culmination of a seven-year project, this volume provides a complete description of American Sign Language (ASL) variation. For four decades, linguists have studied how people from varying regions and backgrounds have different ways of saying the same thing. Noted scholars Ceil Lucas, Robert Bayley, and Clayton Valli led a team of exceptional researchers in applying techniques for analyzing spoken language variation to ASL. Their observations at the phonological, lexical, morphological, and syntactic levels demonstrate that ASL variation correlates with many of the same driving social factors of spoken languages, including age, socioeconomic class, gender, ethnic background, region, and sexual orientation. Internal constraints that mandate variant choices for spoken languages have been compared to ASL as well, with intriguing results. Sociolinguistic Variation in American Sign Language stands alone as the new standard for students and scholars committed to this discipline.

This introductory text celebrates another dimension of diversity in the United States Deaf community -- variation in the way American Sign Language (ASL) is used by Deaf people all across the nation. The different ways people have of saying or signing the same thing defines variation in language. In spoken English, some people say "soda," others say "pop," "coke," or "soft drink; " in ASL, there are many signs for BIRTHDAY, HALLOWEEN, EARLY, and of course, PIZZA. What's Your Sign for PIZZA derives from an extensive seven-year research project in which more than 200 Deaf ASL users representing different ages, genders and ethnic groups from seven different regions were videotaped sharing their signs for everyday vocabulary. This useful text and its accompanying CD begins with an explanation of the basic concepts of language and the structure of sign language, since sign variation abides by the rules governing all human languages. Each part of the text concludes with questions for discussion, and the final section offers three supplemental readings that provide further information on variation in both spoken and signed languages. What's Your Sign for PIZZA also briefly sketches the development of ASL, which explains the relationships between language varieties throughout the country.
