蝦夷方言藻汐草

Batchelor lists oipakari sak among equivalents of “young,” providing an explicit comparison for oypakari sak. The facsimile nevertheless shows シマク, not an unambiguous spelling of sak. Replacing マ with ヤ would be conjectural and is not applied to the transcription. The literal alternative oypakari simak also lacks a secure analysis. No queried complete expression has a corpus match; the dictionary comparison is retained as a guess, without asserting that this source is a copying error.
