This book provides an inside view of the social construction of bilingualism in one of the largest and most disadvantaged Spanish-speaking groups in the United States. It walks readers through a New York Puerto Rican Community and describes the five varieties of Spanish and English that constitute the community's bilingual and multi-dialectal repertoire, the four major communication patterns that predominate in the homes of twenty families with children, and the syntactic features and discourse strategies of so-called "Spanglish".
