The Narragansett language died out in the 19th century, so modern attempts to understand its words have to make use of written sources. The earliest such sources are the writings of English colonists in the 1600s, and at that time the name of the Narragansett people was spelled in a variety of different ways, perhaps attesting to different local pronunciations. The present spelling "Narragansett" was first used by Massachusetts governor John Winthrop in his "History of New England" (1646); but assistant governor Edward Winslow spelled it "Nanohigganset", while Rhode Island preacher Samuel Gorton preferred "Nanhyganset"; Roger Williams, who founded the city of Providence and came into closest contact with the Narragansett people, used a host of different spellings including "Nanhiggonsick", "Nanhigonset", "Nanihiggonsicks", "Nanhiggonsicks", "Narriganset", "Narrogonset", and "Nahigonsicks".
