The cousin is a sister
Each of the people living in the world has its own history, it is deeply rooted in the past. In order to reconnect generations, they make up a genealogical tree, draw tables of kinship. Hundreds of intricate names can be found there, they are all invented in order to refer to a relative, which is not counted in a dozen, especially in families with many children. Remember the entire list is quite difficult, but to know how to properly call even your closest blood people, you must. The cousin is also a close relative.
Borrowing from the West
Where did the name "cousin" come from? This word is borrowed from English. In English-speaking countries the word cousin denotes children from relatives, blood and one-half brothers and sisters of your parents. Simply put, in translation from English "cousin" is "cousin". By the way, the French have a similar in sounding word - cousine.
Those who were born and raised in the Soviet Union or in the territory of the post-Soviet space, realize that the cousin is a cousin, is rather strange. This word was not used by our people, it was inspired by the West. In most of the families, not bothering with fictions, they call cousins just cousins.
How was it in Russia?
Our ancestors also did not know that the cousin is a cousin. Therefore, called such a relative strychka. No less intricate designations were given by our ancestors and to such relatives as cousins on the father. They were called Strychiches. If the relationship took place on the maternal line, then the cousin was called the uez or uychich. All these names are formed from the Old Russian designations of the sisters and brothers of the father (stryi, stryi), as well as the names of the mother brother - ui. Strangely enough, but the mother's sister was called simply and uncomplicatedly - aunt.
