A more thorough explanation:

Collaterals

Collaterals are family members who come from a common ancestor, but are not direct ancestors or descendants. They are relatives such as uncles, aunts, or cousins. Ancestors are parents, grandparents, and great-grandparents.

For example, your uncle is your collateral because he is your parent's brother, but he is not your direct ancestor or descendant. Your cousin is also your collateral because they are the child of your parent's sibling, but they are not your direct ancestor or descendant.

Another example is your great-aunt. She is your grandparent's sister, but she is not your direct ancestor or descendant.

The examples illustrate that collaterals are relatives who come from a common ancestor, but are not direct ancestors or descendants. They are family members such as uncles, aunts, or cousins who are related to you through your parents or grandparents. Collaterals are important in family relationships and can provide support and connection to your extended family.
