蝦夷方言藻汐草

Poho is the documented possessive form of po “son/child,” matching the source’s final ホ. Narrative examples such as e=poho “your son” confirm that use. Popo is a different expression: Nakagawa records gathering together and an infant-language “older brother,” while corpus matches also include a diminutive-like use and a corrected false start. Kirikae also uses popo for a child in an example; that semantic overlap does not justify changing this source’s h to p. The recorded ボホ is retained, with poho as its normalized interpretation.
