Even Latin we have to leave to find the etymological origin of the term brother-in-law that now concerns us. Specifically, it comes from the word "cognatus", which is the result of the sum of two components: the prefix "co-", which can be translated as "with", and the word "gnatus", which is equivalent to "born" .
Brother in law is the spouse's brother or the brother's spouse . It's about a family bond that a person acquires from the marriage of his brother or sister, or if this same person contracts marriage And your partner has brothers.
For example: Charles and Martha they are brothers. Silvia is the wife of Charles and Vicente , the husband of Martha . This means that Charles and Vicente they are brothers-in-law, just like Martha and Silvia .
On the other hand, Silvia (the wife of Charles ) has a brother named Raul . Charles and Raul , therefore, they will also be brothers-in-law. In this way it can be said that Charles He has two brothers-in-law: Vicente (her sister's husband Martha ) and Raul (his wife's brother Silvia ).
This allows us to affirm that the brother-in-law is a form of kinship that arises by affinity. There is no loop of blood that one to the brothers-in-law, but that this kinship is created from the union in marriage of a consanguineous relative. The brother-in-law's kinship implies a legal link and not the existence of a natural or blood reason. For legal purposes, brothers-in-law are second-degree relatives with a preferred collateral relationship line.
The brother-in-law who in Spain, for example, is of maximum relevance in recent years is Iñaki Urdangarín, the brother-in-law of King Felipe VI. And it is that he, who is married to Infanta Cristina, is charged in a series of crimes of money laundering that has caused the monarchy to falter and be attacked by the population. Hence, the monarch, among other things, has decided to remove him from all official acts.
However, we cannot ignore that in some countries of the world it is common for brother-in-law to be used with another meaning. Specifically, that term is used to address friends in an affectionate and affective manner.
Do not forget that there is a Spanish company that is called Grupo Cuñado. In the decade of the 60s it was when it began its activity, which is specialized in the manufacture of all types of tubes or valves, for example, used in industries of various kinds.
Also do not forget that there is an artist whose last name is the word that concerns us. We are referring to Carlos Cuñado, a young artist who stands out for his multidisciplinary nature, since he practices various arts such as painting or photography.
The notion of concumbered On the other hand, it is used to name someone's partner with respect to the spouse of another person's sister. In other words, a person's brother-in-law's partner is their sister-in-law. If we return to our example, Vicente (husband Martha , the sister of Charles ) and Silvia (wife Charles ) are concuined.
