Proto-Eskimoan, Proto-Eskimo, or Proto-Inuit-Yupik, is the reconstructed ancestor of the Eskimo languages. It was spoken by the ancestors of the Yupik and Inuit peoples. It is linguistically related to the Aleut language, and both descend from the Proto-Eskaleut language.
Comparative studies of Eskimo and Aleut languages suggest that the Proto-Eskimoan and Proto-Aleut languages diverged between 4000 and 2000 BCE.
