Usage
What does grandma mean? Grandma is an informal word for grandmother—the mother of a person’s parent. When a mother’s child has their own children, that mother becomes a grandma. The word ma is an informal way to say mother. Grandma is often combined with a name, especially when a person has two grandmothers that they call Grandma, as in Grandma Marg and Grandma Marie. Should grandma be capitalized?Grandma should be capitalized when it’s used as a proper name, as in Please tell Grandma that I miss her. But grandma does not need to be capitalized when it’s simply used as a way to refer to her, as in Please tell my grandma that I miss her. Example: It doesn’t matter what you call your grandma, as long as you call her.
