Comments: ТМС 2, 95, 131. Length in the dialectal Nanai form (quoted from Onenko) is unclear, probably a misrecording. The Manchu form is peculiar: one would wish it to be < Mong. sira morin 'white horse', but the vocalization is extremely strange. On the other hand, Kor. sjǝra măr (see Lee 1958, 119) makes it quite probable that such a form did, indeed, exist in Manchu, but probably got mixed up later with the original root *sür-.
