Individual chapters analyze particular contact situations: in Spain, contact with Basque, Catalan, Valencian, and Galician; in Mexico, Central, and South America, contact with Nahuatl, Maya, Quechua, Aimara, and Guarani; in the Southern Cone, contact with other principle European languages such as Portuguese, Italian, English, German, and Danish; in the United States, contact with English. A separate chapter explores issues of creolization in the Philippines and the Americas and highlights the historical influence of African languages on Spanish, primarily in the Caribbean and Equatorial Guinea.

Written in Spanish, this detailed synthesis of wide-ranging research will be a valuable resource for scholars of Hispanic linguistics, language contact, and sociolinguistics.
