It is one of the four Yupik languages, along with Central [Siberian Yupik language|Central Siberian Yupik], Central [Alaskan Yup'ik language|Central Alaskan Yup'ik] and Pacific Gulf Yupik.
Linguistically, it is intermediate between Central Siberian Yupik and Central Alaskan Yup'ik.
Morphology
Chart example of the oblique case:| Case | singular | dual | plural |

| Abl. / Instr. | məɣ | ɣnəɣ | nəɣ |

The non-possessed endings in the chart may cause a base-final 'weak' ʀ to drop with compensatory gemination in Inu. Initial m reflects the singular relative marker. The forms with initial n are combined to produce possessed oblique with the corresponding absolutive endings in the 3rd person case but with variants of the relative endings for the other persons.
In proto-Eskimo, *ŋ was often dropped within morphemes except when next to *ə. *ŋ is also dropped under productive velar dropping, and *ana becomes ii in these areas.
