The Chukotko-Kamchatko-Amuric or Chukotko-Kamchatkan-Amuric languages form a hypothetical language family including Nivkh and Chukotko-Kamchatkan. A relationship between these two language groups was proposed by Michael Fortescue in a 2011 paper. [note 1] He theorized that their common ancestor might have been spoken around 4000 years ago. [1] However Glottolog says that the evidence is insufficient to conclude a genealogical relationship between Nivkh and Chukotko-Kamchatkan. [2]

Chukotko-Kamchatkan and Nivkh have dual/plural distinction, however it has been lost in Chukchi.
Chukotko-Kamchatkan also has a "singulative" ending, and traces of a singulative ending in Nivkh might be seen.
