Who am I the husband of my husband's sister?

When we get married, sometimes we do not even understand,how much we push the boundaries of our family. Not only new family members, such as mother-in-law, father-in-law (husband of parents), mother-in-law and father-in-law (parents' wives), and other close relatives, such as sister's husband or brother's wife, children of sisters, brothers, If you, like me, have pondered over what I am the husband of my husband's sister, the following explanation will be of interest to you.

Let's think logically: the sister of the husband in the people is called "sister-in-law", and the husband of your sister, daughter or sister-in-law is called "son-in-law". Thus, it turns out that you should call this person a son-in-law, although you can also refer to him as a "brother-in-law". The bottom line is that the brother-in-law is the husband of the brother-in-law, that is, the husband of your wife's sister. However, in modern society it is perfectly permissible to call the husband of your husband's sister (your wife) a brother-in-law. Thus, we involuntarily answered one more question about kinship, who the sister's husband is to his brother.

As a result, in order not to be confused in this kind of family ties, call such relatives as brothers-in-law, so everyone will understand.
