蝦夷方言藻汐草

The facsimile supports イトユタ. Itoyuta retains its ユ vowel, which the former itoyta omitted; hoskinuman remains a modern comparison for the initial ホシケヌマニ. Hirayama prints the competing ending イタユタ, tested as itayuta, but its comparison explains only the first element. Etoko ta “previously/before” suggests a possible relative-day construction, requiring unexplained イ／エ and ユ／コ differences. Hoskiannuman is documented for three days ago, although the Mukawa extracts give both おととい and 一昨昨日. It has a different structure. Etoyta “plant/sow” does not explain the day gloss. No complete expression or tail meaning is established.
