The tribe has begun language revival efforts, based on early-20th-century books and manuscripts, and new teaching programs. The Narragansett spoke a "Y-dialect", similar enough to the "N-dialects" of the Massachusett and Wampanoag to be mutually intelligible. Other Y-dialects include the Shinnecock and Pequot languages spoken historically by tribes on Long Island and in Connecticut, respectively.
In the 17th century, Roger Williams, a co-founder of Rhode Island, learned the tribe's language. He documented it in his 1643 work, A Key Into the Language of America. Williams gave the tribe's name as Nanhigganeuck.
According to Dr. Frank Waabu O'Brien, who has taught the language for the Aquidneck Indian Council, "Narragansett was understood throughout New England." He states that "Scholars refer to Massachusett and Narragansett as dialects of the same language," and has created a diagram of the relationships between the languages as described in their source documentation[3][4] as well as instructional materials.[5] A Facebook page entitled "Speaking Our Narragansett Language" has provided alphabet and vocabulary of the language.
