A brother by marriage
A person's 'brother-in-law' is his/her sister's husband, or spouse's brother.
There is some debate over whether the husband of a person's sister-in-law is "brother-in-law" or "brother-in-law by marriage", however, most legal definitions indicate that a sibling through marriage is a "brother-in-law" or "sister-in-law".
The term is often misapplied to the husband of a person's sister-in-law; the correct term for such a relationship is "brother-in-law by marriage."
The plural form is "brothers-in-law".
