Usage
What does grandmother mean? A grandmother is the mother of a person’s parent. When a mother’s child has their own children, that mother becomes a grandmother. Less commonly, grandmother can be used in a general way to refer to a female ancestor, as in This would not be possible without the contributions of those who came before us, our many grandmothers. Should grandmother be capitalized?Grandmother should be capitalized when it’s used as a proper name, as in Please tell Grandmother that I miss her. But grandmother does not need to be capitalized when it’s simply used as a way to refer to her, as in Please tell my grandmother that I miss her. Example: It doesn’t matter what you call your grandmother, as long as you call her.
Etymology
Origin of grandmother
late Middle English word dating back to 1375–1425; see origin at grand-, mother 1
Explanation
Your grandmother is your mom or dad's mother. In many traditional cultures, a grandmother lives with her adult child's family and helps raise her grandchildren. Everyone has two biological grandmothers, maternal (your mother's mother) and paternal (your father's mother). If you're lucky, your grandmother is someone you get to know well. One of the most well-known fictional grandmothers appears in "Little Red Riding Hood," the fairy tale in which a wolf disguises himself as Red Riding Hood's grandmother in an attempt to fool her into being eaten.
