Paraguay is a bilingual nation. Spanish, the dominant language, is taught in the schools and is spoken by slightly more than half of the people. However, the great majority of Paraguayans speak Guaraní, an Amerindian language that evolved from the southern dialect of the Tupi-Guaraní group. It is also the language of widely esteemed literature, drama, and popular music. Both Spanish and Guaraní are official languages.
