No, that is not the way a relationship like their's works.
Your husband's brother is your brother-in-law. Your brother-in-law's wife is not related to you, but is your husband's sister-in-law. The sister of your husband's sister-in-law is not related to you or to your husband.
In English, your brother's daughter is called your niece. Your sister's daughter is also called your niece.You are her aunt if you are a woman or her uncleif you are a man.
You would call your wife's sister your sister-in-law. If your wife would have a brother he would be your brother-in-law. It is the same thing for a husband's siblings. Your wife's mother would be your mother-in-law. Her father would be father-in-law.
A woman might be jealous that a brother and sister have a more intimate relationship, which is natural in most cases because siblings grow up together. But flirting with a sister-in-law could be accepted as a joke and not a serious action that threatens the husband-wife relationship.
Sister-in-law. same as your brother's wife.
Your husband's brother's wife is your husband's sister-in-law, but is not considered to be related to you. But I have the same thing, in my family, I consider my husbands, brothers girl friends as my sister, even though we are not really related but we both still say we are sisters!! so really you can pick if you want them to be your sister, but they will never actually be related to by name, or anything
Your wife's brother is your brother-in-law. Your brother-in-law's wife is not related to you, and the same applies to her sister.
I believe a single home fight. As in a husband and wife, or a brother and sister ect. Anyone that lives in the same home..
You can't charge a husband and wife for the same crime.
Your sister's sister-in-law is your sister-in-law, but only if your sister's sister-in-law is the wife of your brother.If your sister's sister-in-law is the sister of your sister's husband, then she is not your sister-in-law and is not related to you at all.
Same as his wife's
Your sister's husband is your brother-in-law. It does not matter whether you speak of your elder sister or another sister, the same term is used for the husband of any one of your sisters.
