Taíno is a language historically spoken by the Taíno people of the Caribbean. At the time of Spanish colonization, it was the principal language throughout the Caribbean. Classic Taíno (Taíno proper) was the native language of the northern Leeward Islands, Puerto Rico, the Turks and Caicos Islands, and most of Hispaniola, and was expanding into Cuba. Ciboney is essentially unattested, but colonial sources suggest it was a dialect of Taíno. It was the language of westernmost Hispaniola, the Bahamas, Jamaica, and most of Cuba.
