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.

Where does granddad come from?

The first records of the word granddad come from the 1700s. The word dad is an informal way to say father. The prefix grand- is used in family terms to indicate a person who is one generation removed, as in grandparent and grandchild. (The prefix great- indicates yet another generation, as in great-grandpa.)

Grandfathers often have special bonds with their grandchildren (who they’re known to spoil with love, affection, and candy). It’s common for grandchildren to refer to their grandfathers with informal names. Grandpa is perhaps the most common variant of the word grandfather, but there are many others, including granddad, grandpop, grampa, gramps, grandpapa, and grandpappy. Many families have their own specific version, such as Pop-Pop, Poppy, and Pa Pa.
