Who is the husband's brother?
From the very first moments of life we are insurrounded by their close relatives. Mother and father, sisters and brothers, grandfathers and grandmothers - these people are our closest relatives during all the years. However, by marrying, or marrying, we significantly expand the circle of close people, and find out who is whom whom it happens to be quite difficult.
What does the husband's brother have to do with his wife?
A girl first married, often lost innames and definitions of new relatives on the part of her husband and if she is more or less familiar with the concepts of "mother-in-law" and "father-in-law", then such definitions as "sister-in-law" or "brother-in-law" often put a young married woman at a dead end.
But in order to understand theintricacies of kinship relations much effort is not needed. It is just not too lazy and the question, for example, who is the brother of her husband, look for the answer in the dictionary. Then you will remember once and for all that if your husband has siblings, then they are your brother-in-law, you, in turn, are their daughter-in-law. The same dictionary, incidentally, tells us that in the genitive case of the plural, the word "devere" is used.
