蝦夷方言藻汐草

I= is retained cautiously because Tamura and Nakagawa document a respectful second-person object use, alongside inclusive and narrative first-person uses. It is not a general independent singular “you.” E= is the ordinary second-person prefix and remains an alternative if イ represents its vowel historically. The isolated source gloss supplies no syntax or social context to choose securely. Corpus examples of i=kor retained here mean “me,” so they do not verify the respectful second-person analysis. Prefix-query counts are boundary-limited retrieval, not total grammatical occurrences.
