Nivkh is not known to be related to any other language, making it a
language isolate. For convenience, it may be included in the geographical group of
Paleosiberian languages. Many words in the Nivkh languages bear a certain resemblance to words of similar meaning in other
Paleosiberian languages,
Ainu,
Korean, or
Tungusic languages, but no regular sound correspondences have been discovered to systematically account for the vocabularies of these various families, so any lexical similarities are considered to be due to chance or to borrowing.
Michael Fortescue suggested in 1998 that Nivkh might be related to the
Mosan languages of North America. Later, in 2011, he argued that Nivkh, which he referred to as an "isolated Amuric language", was related to the
Chukotko-Kamchatkan languages, forming a
Chukotko-Kamchatkan–Amuric language family. However,
Glottolog considers the evidence to be "insufficient". In 2015,
Sergei Nikolaev argued in two papers for a systematic relationship between Nivkh and the
Algic languages of North America, and a more distant relationship between these two together and the
Wakashan languages of coastal
British Columbia. The Nivkh languages are included in the widely rejected
Eurasiatic languages hypothesis by
Joseph Greenberg. An automated computational analysis (
ASJP 4) by Müller et al. (2013) found lexical similarities among Nivkh,
Mongolic, and
Tungusic, likely due to lexical borrowings. Hudson & Robbeets (2020) conjectured that a language that resembles Nivkh was once distributed in
Korea and became the
substratum of
Koreanic languages.
Kim Bang-han proposed that
placename glosses in the Samguk sagi reflect the original language of the Korean peninsula and a component in the formation of both Korean and Japanese. He proposed that this language was related to Nivkh.
Juha Janhunen suggests the possibility that similar consonant stop systems in Koreanic and Nivkh may be due to ancient contact. == History ==
