Proto-Altaic: *ǯi̯aru(kV)
Meaning: a k. of foliage tree, alder
Russian meaning: вид лиственного дерева, ольха
Comments: The etymology is possible, though somewhat problematic. Whether the Japanese Daphnyphyllum may be equated with the Turkic and TM alder is a botanical question requiring additional clarification; as for the equation of the Turkic and TM forms, it is possible if we assume PTM *ǯugde- < *ǯurke, with the original velar suffix reinterpreted as part of the root.
