What is the girl whose uncle called her grandson shouting?

It's called granddaughter

Because: Your mother and your uncle are the same age.

You and your uncle's children are the same age.

Your daughter and your uncle's children are of the same age.

Your daughter is separated from your uncle by a generation, and your daughter belongs to her grandson. Because my uncle belongs to my grandmother's family. So your daughter belongs to her grandson. For this reason, your uncle should call your daughter's granddaughter.
