シユ〳〵タイ
Ainu「柳原」
susutaymedium
The repetition gives シユシユタイ, matching Hirayama’s source headword. Tamura and Kayano identify susu as willow and tay as a wooded stand, supporting susutay for 柳原. This is stronger evidence than the earlier fuzzy match to the companion spelling シュタヱ. The spaced susu tay is a segmentation comparison. Neither full-form corpus query matches, so the compound interpretation rests on the source and attested components.
