In Hawaii the honorific for grandma is Tutu. It's phonetically simple for little kids (keiki) to manage in their early years......and it sticks. But it's doubtful that it's pronunciation derived from the Hawaiian language since there is no T consonant. The word for grandmother is Kuku wahine, the 'Tutu' prounciation is most likely Samoan or Tahitian.

Ah, like “kapu” in Hawaiian, and “taboo” from - Fiji maybe? Or not.
