Usage
What does granddad mean? Granddad is an informal word for grandfather—the father of a person’s parent. When a father’s child has their own children, that father becomes a granddad. Granddad should be capitalized when it’s used as a proper name, as in Please tell Granddad that I miss him. But granddad does not need to be capitalized when it’s simply used as a way to refer to him, as in Please tell my granddad that I miss him. Example: It doesn’t matter what you call your granddad, as long as you call him.
