This edited volume, based on papers presented at the 2017 Georgetown University Round Table on Language and Linguistics (GURT), approaches the study of language variation from a variety of angles. Language variation research asks broad questions such as, "Why are languages' grammatical structures different from one another?" as well as more specific word-level questions such as, "Why are words that are pronounced differently still recognized to be the same words?" Too often, research on variation has been siloed based on the particular question—sociolinguists do not talk to historical linguists, who do not talk to phoneticians, and so on. This edited volume seeks to bring discussions from different subfields of linguistics together to explore language variation in a broader sense and acknowledge the complexity and interwoven nature of variation itself.

Twenty-four linguists analyze natural and social differences in language form, use, and attitudes.

Thirty-three million people in the United States speak some variety of Spanish, making it the second most used language in the country. Some of these people are recent immigrants from many different countries who have brought with them the linguistic traits of their homelands, while others come from families who have lived in this country for hundreds of years. John M. Lipski traces the importance of the Spanish language in the United States and presents an overview of the major varieties of Spanish that are spoken there.

Varieties of Spanish in the United States provides—in a single volume—useful descriptions of the distinguishing characteristics of the major varieties, from Cuban and Puerto Rican, through Mexican and various Central American strains, to the traditional varieties dating back to the sixteenth and eighteenth centuries found in New Mexico and Louisiana. Each profile includes a concise sketch of the historical background of each Spanish-speaking group; current demographic information; its sociolinguistic configurations; and information about the phonetics, morphology, syntax, lexicon, and each group's interactions with English and other varieties of Spanish. Lipski also outlines the scholarship that documents the variation and richness of these varieties, and he probes the phenomenon popularly known as "Spanglish."

The distillation of an entire academic career spent investigating and promoting the Spanish language in the United States, this valuable reference for teachers, scholars, students, and interested bystanders serves as a testimony to the vitality and legitimacy of the Spanish language in the United States. It is recommended for courses on Spanish in the United States, Spanish dialectology and sociolinguistics, and teaching Spanish to heritage speakers.
