Kerek used to be classified as a dialect of Chukchee, but it has idiosyncratic features suggesting, on the one hand, a non-Chukchee-Koryak (probably Eskimo-Aleut) substrate, and, on the other hand, transitionality towards Koryak; the superficial similarity of Kerek with Chukchee can also be due to secondary Chukchee areal influence on Kerek.
