This is my first question here so please be gentle with me. I have a relative staying with me from Mississippi who says things about manners and behavior in reference to his grandma-ma. It goes a little like.
My grandma-ma always said X.
My grandma-ma raised me better than to do X.
Now I've just kind of assumed that grandma-ma was a southern way of saying grandma but recently I've been lead to believe that it refers to a great-grandmother.
Sadly my relative has continued their travels and I don't have a way of touching base with them to ask.
Can someone explain to me this difference and maybe include a source where I can find out more about how it came to be. Running a google search on this kind of took me to a bunch of places that didn't answer my question.
