I think its toaina !
There's no literal translation for grandpa in the Samoan language. Grandchildren would either simply say Papa or something similar. If you are after an "actual" translation (i.e, if you were explaining your relation with your grandpa to another person) you would say "O le tama o lo'u tama"...Bearing in mind that you are dragging the final "a" in the word tama. So it sounds like Ta-Maaah.
