[1][2][3] Speakers of the Chevak subdialect refer to themselves as Cupʼik (as opposed to Yupʼik), while speakers of the Hooper Bay subdialect refer to themselves as Yupʼik (not Cupʼik), as in the Yukon-Kuskokwim dialect.The Central Alaskan Yupik who live in the village of Chevak call themselves Cupʼik (plural Cupʼit), whereas those who live on Nunivak Island (Nuniwar in Nunivak Cupʼig, Nunivaaq in Central Yupʼik) call themselves Cupʼig (plural Cupʼit), the spelling differences serving as a self-designated cultural identifier between the two groups.The Cupʼik dialect is readily distinguished from other dialects of Yupʼik by the pronunciation of the Yupʼik "y" sound as a "ch" sound (represented by the letter "c"), and by some fundamental differences in the basic vocabulary.Published recognition of Hooper Bay-Chevak as a morphologically distinct dialect of Yupʼik seems to begin with Michael E. Krauss in 1973,[4] although the fundamental differences between the dialects were common knowledge among native speakers.Before 1950 formal education for students in Chevak took place in the Qaygiq[5] (semi-underground men's community house), and in the homes of the people.
