How do you say second cousin in French?

There isn't a direct translation for "second cousin" in French. Instead, you would say:

* "Cousin au second degré" (literally "cousin of the second degree")

This phrase is used to refer to any relative who is two generations removed from you.

For example, if your parent and your cousin's parent are siblings, you are first cousins. If your grandparent and your cousin's grandparent are siblings, you are second cousins.
