Spanglish (also referred to as Espanglish, Espaninglish, and Casteinglés, among other appellations) is the hybrid language that results from the cross-fertilization between Spanish and English and, more broadly, between traits in Anglo and Hispanic civilizations. A byproduct of mestizaje with distinct linguistic varieties (Tex-Mex, Chicano, Nuyorrican, Cubonics, Dominicanish, etc.), it is used by millions in the United States, where Latinas/os are the largest and fastest-growing minority, as well as throughout Latin America, Spain, and other parts of the world. Spanglish, like any other language, has acquired its present characteristics through a slow development, in this case one lasting almost 200 years. Seen traditionally as a way for immigrants to communicate, it is actually used by all social classes; on radio, TV, theater, movies, Broadway musicals, the Internet, and social media; in political speeches and religious sermons; in sports and marketing; in the banking and food industries; and in literature, including young adult and children’s books. There are also full or partial translations of literary classics like Don Quixote of La Mancha, Hamlet, Alice in Wonderland, and The Little Prince.
