Mairasi cannot be linked to other families by its pronouns. However, Voorhoeve (1975) links it to the
Sumeri (Tanah Merah) language, either a language isolate or an independent branch of the
Trans–New Guinea family. Pawley and Hammarström (2018) do not consider there to be sufficient evidence for the Mairasi languages to be classified as part of
Trans-New Guinea, though they do note the following lexical resemblance between Mairasi, Semimi, and
proto-Trans-New Guinea. :
Mairasi ooro and
Semimi okoranda ‘leg’ <
proto-Trans-New Guinea *k(a,o)nd(a,o)C ‘leg’
