Cousin in Law
I think that you call them your cousin in law because its pretty much the same concept as a sister in law... its your husbands cousin so it would be a cousin in law
Your cousin in law
2nd cousin or 2nd cousin in law.
Your sister's husband is your brother-in-law.
Nomral Only you first cousin spouse is realated to you and thats cousin in lawSo i guest you can say 2nd cousin in law.
Your cousin could legally become your step-sister. Your cousin could legally become your sister if she were adopted by your mother or father. This is because by law persons adopted by others are considered children of the adopting persons.
Let's see if we can unravel this. Your sister's husband's father's brother is your sister's husband's uncle. The uncle's daughter is your sister's husband's cousin. There is no relationship to your sister, unless your sister wants to call her a cousin-in-law. To break it down to its simplest terms: She is your brother-in-law's cousin and no relationship to you.
Though I may be wrong, im sure a 2nd cousin would be a "cousin in law" of your cousin. No blood relation at all, therefore if he or she is cute, go for it, but ask your cousin to be polite. Or dont, I personally dont care.
If your the wife, it's you cousin in law. It's your husband's cousin because the cousin's sister is just another cousin to your husband. Since the cousin isn't exactly related to you, it's your cousin "in law".
The English language has not special name for the cousins of your spouse. You could just call them by their first names like you would your friends. If you really like them, you could decide to call them your cousins.
Cousin in law its same as brother or sister in law.
