A granddaughter is someone's child who has a mother and that mother is also this person's daughter. A granddaughter can be your own or someone else's.
When people talk about their granddaughters, they often do so with pride. They might mention what she's been up to lately, like learning how to ride a bike or getting good grades in school. Some grandparents spend a lot of time with their granddaughters and are very involved in their lives. For example, they might take her to the park for playdates or help her with her homework. The relationship between a grandparent and their granddaughter is often close and loving, even if they don't live together.
