How do you say grandpa and grandma in Quebec?
Grandma- Grandmére Grandpa-Grandpére
It depends. If you can trade their proper names for their titles in the sentence, then you should probably capitalize them. For example: "Hal and Ethel visited us. " "Grandpa and Grandma visited us." But you probably wouldn't say, "They went to see their Hal and Ethel." Instead, you'd say, "They went to see their grandpa and grandma." So you wouldn't capitalize in that case.
