蝦夷方言藻汐草

Hapo directly matches the source’s mother gloss. Tamura documents both reference and address uses; the isolated entry does not choose between them. Chiri records father or elder-sibling uses in other localities, so the meaning is not identical across all dialects. Habo occurs in older corpus spelling, while modern p is selected. Retained mother contexts support this entry; metaphoric “earth is our mother” examples are not independent descriptions of a family relationship.
