All answers are wrong - you cannot rely on modern Russian spelling and pronunciation. It has nothing to do with Erzya - onierdzat. Erzya is a late russification. The closest Kuzmin is Ryazan and rezat - one-kin words. She Rjgezan - from the masculine name or nickname Rjez - cut out, not cut off In the Slavic world, dozens of cities with the name cut off
