My family is French-Canadian and I've always referred to my grandparents as mémère and pépère. I've always pronounced this like mémé and pépé, though, despite the spelling. Recently I've come across some articles indicating that the words mémère and pépère can be insulting. I've always used it to mean grandma and grandpa. Is it insulting if pronounced the way it's spelled? Is it still insulting if pronounced like mémé and pépé, despite the spelling?
