Is your brothers wife's sister your sister-in-law?

Answer 1

Your sister-in-law is either the wife of your brother or the sister of your spouse. Your brother-in-law is either the husband of your sister or the brother of your spouse.

So your brother-in-law's wife is either your sister or is not related to you.

Some people incorrectly refer to a brother-in-law's wife as a sister-in-law.

Answer 2

Your sister-in-law may be your brother's wife. In that case, her husband is your brother, so his sister would be your sister. Your sister-in-law may also be the sister of your husband. In that case, her husband's sister is no relation to you.

Answer 3

Your wife's brother is your brother-in-law. The wife of your brother-in-law is not considered to be related to you and, in English usage, is not your sister-in-law.

Answer 4

Your sister's husband's brother is her brother-in-law but is not related to you.

Answer 5

No, that person is not related to you. The only brother-in-law you have is your sister's husband or your spouse's brother.

Answer 6

No. In the English language cultures your husband's brother is your brother-in-law but his wife is not related to you.

Answer 7

No. She is your brother's sister-in-law.

Answer 8

Yes.
