Could the Slavs on this group give me a quick and dirty way to form the English adjective for the Nenets language? Is 'Nenetsy' the Russian adjective for this Uralic language?
I'm looking for 'Nenetsic', a la Germanic Slavic Italic Hellenic etc-ic.
The Russian adjective looks like Nenetsky, from Nentsy 'the Nenets people'. Why not Nenetsian?

Why not. But it looks funny, and makes you do funny things with the stress. That final S in 'Nenets' presents some emotional difficulties for certain of us AmE speakers.
