Note

Also Selaru ébu ‘grandparent, grandchild’. For the history and function of the prefix *t- and the suffix *-q in Austronesian kinship terms, cf. Blust (1979). From the discussion in that article it will be apparent that the PMP status of *t-impu implies a PMP form *impu, even if direct attestation of the unaffixed form in both WMP and CEMP languages is lacking.
