What does one call the wife of the brother of their husband?


Quick Answer

Full Answer

The term brother-in-law, sister-in-law or sibling-in-law is most commonly used to refer to the brother or sister of one's husband or wife. However, when a spouse's sibling gets married, the same term is used to describe the relationship between the two spouses. This is the term that is used in the United States and in many other English-speaking cultures, but some cultural traditions may use different language to describe the wife of one's brother-in-law. If one's brother-in-law divorces his wife, that woman can be referred to as an ex-sister-in-law. However, in informal situations and contexts in which keeping things simple is desirable, it may be easiest for the various spouses of a group of siblings to simply refer to each other by their first names.
