орос

Buryat Wikipedia has an article on:

ородууд

Wikipedia ^bxr

Borrowed from Classical Mongolian ᠣᠷᠤᠰ᠋ (orus), from Middle Mongol 斡羅思 (orus), from Old East Slavic Русь (Rusĭ). In Buryat, an original final *-s has to be historically changed to -d, so phonetically non-native орос should be a Mongolian borrowing and doublet of its native synonym ород (orod).

• IPA^(key): /ɔ.rɔs/,

орос • (oros) (^??? please provide spelling!)

1. Synonym of ород (orod, “Russian”)
