There are at least two hypotheses about the origin of the word:
1. The first element эр- (er-) or эрь- (eŕ-) is from Proto-Uralic *irkä or *ürkä (“man, son, boy”), whence -ar in Hungarian magyar (“Hungarian”), Eastern Mari эрге (erge, “son, boy”) and Finnish yrkä (“groom”), yrkö (“man”).
2. The word derived from Proto-Mordvinic *eŕams (“to live”); compare Erzya эряза (eŕaza), Moksha (j)äŕaza (“lively”).[1] However, *eŕams itself may be related to *irkä~*ürkä.
In the both cases -зя (-źa) may be a noun-forming suffix (from *-za).
