Taíno is a poorly-attested Arawakan language that was spoken by the Taíno people of the Caribbean. At the time of Spanish contact, 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 it was expanding into Cuba. Ciboney is essentially unattested, but colonial sources suggest that it was a similar language to the Taíno language and was spoken in westernmost Hispaniola, the Bahamas, Jamaica, and most of Cuba.

Taíno dialects, among other Pre-Columbian languages of the Antilles
By the late 15th century, Taíno had displaced earlier languages except in western Cuba and pockets in Hispaniola. As the Taíno culture declined during Spanish colonization, the language was replaced by Spanish and other European languages. It is believed to have been extinct within 100 years of contact but possibly continued to be spoken in isolated pockets in the Caribbean until the late 19th century. As the first indigenous language encountered by Europeans in the New World, it was a major source of new words borrowed into European languages.
Granberry & Vescelius (2004) distinguish two dialects, one on Hispaniola and further east, and the other on Hispaniola and further west.
- Classic (Eastern) Taíno, spoken in Classic Taíno and Eastern Taíno cultural areas. These were the Leeward Islands north of Guadeloupe, Puerto Rico, central Hispaniola, and the Turks & Caicos (from an expansion in ca. 1200). Classic Taíno was expanding into eastern and even central Cuba at the time of the Spanish Conquest, perhaps from people fleeing the Spanish in Hispaniola.
- Ciboney (Western) Taíno, spoken in Ciboney and Lucayan cultural areas. These were most of Cuba, Jamaica, western Hispaniola, and the Bahamas.
Columbus says that from Bahama to Cuba, Boriquen to Jamaica, the same language was spoken in various slight dialects, but understood by all.
There was also a flap [ɾ], which appears to have been an allophone of /d/.
A distinction between /ɛ/ and /e/ is suggested by Spanish transcriptions of e vs ei/ey, as in ceiba "ceiba". The /e/ is written ei or final é in modern reconstructions. There was also a high back vowel [u], which was often interchangeable with /o/ and may have been an allophone.
There was a parallel set of nasal vowels. The only consonant at the end of a syllable or of a word was /s/.
Taíno is not well attested. Nouns appear to have had noun-class suffixes, as in other Arawakan languages. Attested Taíno possessive prefixes are da- 'my', wa- 'our', li- 'his' (sometimes with a different vowel), and to-, tu- 'her'.
Verb-designating affixes are a-, ka-, -a, -ka, -nV in which "V" is an unknown or changeable vowel. This suggests that, like many other Arawakan languages, verbal conjugation for a subject resembled the possessive prefixes on nouns.
The Taíno language had an SVO word order which might be hard to see when copulas are being used. Boriken dawaria ("I-[Puerto Rico]-from"). Taíno has lost some agglutinate features due to the overwhelming influence of Spanish.
The negation prefix is ma- meanwhile the attributive prefix is ka- as in makabuka "it is not important or not important". But literally means "Without a past"
Some conjugated verbs include Daka (I am), Waiba (We go), Warike (We see)
Attested object suffix includes -wo (we, us) as in Ahiyawoka (Speak to us) 
English words derived from Taíno are: canoe, cassava, cay, hammock, hurricane, iguana, macana, maize, and potato, as well as possibly mangrove, tobacco, and savanna.:229
Taíno loanwords in Spanish are: agutí, ají, cacique, maguey, nigua, tiburón, and tuna, as well as the previous English words in their Spanish form.
