Etymology
Derived from. However, the expected form would be such rather than. According to EDAL, the existing form reflect the verbal stem *pubu- and the derived noun *pubu-pu(n) (with some later confusion because of the loss of *-b-).

Almost all of the descendants obviously reflect or. There are also descendants who preserved the stem *pū-.

Compare also Proto-Nivkh (Whence 🇨🇬), likely a Tungusic borrowing.
