In what language does Vava mean Grandmother and Papu grandfather?

"Vava" and "Papu" are not standard terms for grandmother and grandfather in any widely recognized language. They might be terms of endearment or family nicknames specific to a particular family or region.

To determine the language, we would need more context, such as:

* Origin of the family: Where are the people who use these terms from?

* Specific language or dialect: Do they speak a specific language or dialect within their region?

* Other family terms: Are there other terms for grandparents or other family members in the same language?

Without this context, it's impossible to say definitively what language "Vava" and "Papu" are from.
