I'm aware, but wouldn't it be better just to use one term for everything? I mean every other page that I can think of uses the term "Great Uncle" (or "Adoptive Great Uncle"). —This unsigned comment was made by Entrancement (talk • contribs) .
Then you're not looking it up right. Nawaki, Tsunade, Boruto, Himawari, Sasori, all use "granduncle". In fact, the only two articles that use "great uncle" are Shinki's and Shikadai's, because those had to be entered manually, as being adopted and the lack of a parent character for Karura and Yashamaru means those two don't get automatically added for them. Even for Nawaki, Tsunade, and Sasori, they were manually entered as granduncle. I'm changing Shinki's and Shikadai's to match. Also, sign you talk page edits from now on.

If I may add my two cents "Great x" is more commonplace in the English UK language that we use. Grandparents are really the only time the word grand is used in most cases.—Cerez365(talk) 15:10, June 10, 2018 (UTC)
