“Se nou de a ak papa papa l ki te la”. For “papa papa” isn’t it the same as saying granpapa? if yes, then why not say granpapa? Is the same used for manman too? And also, can I say “gran gran grann mwen” for “great great grandmother” or should I use “manman manman”

You can use papa papa, granpapa, or granpè

 Or manman manman, grann, or granmè

It makes more sense, to me,  saying  “manman manman grann mwen” .
