An granddad is your grandfather, the father of your parent.
The word "granddad" is often used as a friendly and informal way to refer to someone's grandfather. Many people use it when talking about their own grandfathers or when addressing an older man they know well. You might hear someone say, "My granddad always takes me fishing on his days off," or "Granddad loves baking cookies for the family." It's a common term in many families and is often used by children to refer to their grandparents in conversation with friends or siblings.
