Naukan Yupik language[3] or Naukan Siberian Yupik language (Naukan Yupik: Нывуӄаӷмистун; Nuvuqaghmiistun) is a critically endangered Eskimo language spoken by c. 70 Naukan persons (нывуӄаӷмит) on the Chukotka peninsula.

[4] Chart example of the oblique case: 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 (k or t) 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.
