I can provide the general terminology used to refer to the children of your uncle or aunt.
The children of your uncle or aunt are called your cousins. There are two types of cousins:
- First cousins: These are the children of your parents' siblings (your aunts or uncles).
- Second cousins: These are the children of your parents' first cousins. In other words, they are the grandchildren of your grandparents' siblings.
Cousins are considered part of your extended family and are often close in age to you, which can lead to strong bonds and shared experiences.
