affinities


The term has a wide variety of meanings depending on the perspective or discipline from which it is evaluated. In general terms, affinities are similarities, kinships, resemblances or approximations between two or more things. In that sense, there may be affinities between two languages ​​(linguistic affinities), as well as between two people.

One of the uses of the term even refers to the kinship that a person has with the family of their spouse, when they join in marriage. An example of this would be the kinship between the father-in-law and his daughter-in-law, known as political kinship.

The most common use given to affinities refers to when two or more people realize that they coincide in tastes, opinions or characters, which produces feelings of sympathy, attraction or compatibility in them, which can trigger what is known as friendship. and love, between individuals.

These would be the social affinities, which can be: sports, political, religious, professional or philosophical.

From a psychological perspective, affinities go beyond the similarities or meeting points between individuals, since it is stated that one can have an affinity for certain things or inanimate objects. An example of this could be the affinity for a specific color, which motivates him to dress in that color, acquire objects of that color, or paint his home in that color, since he identifies with it and feels fulfilled.

In this way, it can be observed how man, since his primitive times, has sought to unite or group with those who share affinities and, on the contrary, distances himself from those who have thoughts, tastes or considerations contrary to those he or she possesses.

On the other hand, there are the definitions granted by discipline. In chemistry, affinity is defined as the tendency for two or more compounds or chemical elements to combine with each other. An example of this is the affinity that halogen elements and alkali metals have.

Also, there is the semantic affinity that refers to the analogy or proximity that is established between words that share meaning or have a very similar one, which are known as synonyms.
