蝦夷方言藻汐草

Batchelor directly records Tutan “next” with a next-door example, supporting the full selected form and raising confidence to medium. Tamura and Kayano document tutanu for next or following, including sequence rather than geographical proximity. That difference leaves the match to 近所 qualified. Tutan has no exact corpus hit; the numerous tutanu examples do not establish final-vowel loss here. The source’s marked initial glyph can be read as historical ツ゚; プ is a visual alternative, so putan is compared without correcting the transcription.
