Book excerpt: 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.
