It refers to the first language that an individual born in a certain nation will learn and develop. Basically, it is acquired through interaction with the environment that surrounds the subject, since an infant has the ability to remember words that are mentioned very frequently (skill that is not lost when growing up), so it evaluates, in a way, the use that can be given to it and in what moments to use it, this being, however, a bit opaque in the future because the words are used almost automatically and without much awareness.
If more languages are mastered over time, they cannot be considered motherly, even if it is acquired through the intervention of people present in the environment and if it is the one used for daily communication. However, in some countries, two languages are mastered, for example, in Catalonia, where young people grow up learning Catalan, a Romance language from Latin, the result of the fragmentation of Latin at the fall of the Roman Empire, as well as Spanish is taught; This type of situation not only occurs in these regions, it also occurs in different countries on the globe, such as Paraguay and Canada.
According to different linguists, such as Noam Chomsky, the first language can be learned until around 12 years of age, a sufficient period to absorb what is considered the basic language for day-to-day communication. However, it is possible to delve into all its splendor, trying to understand the different aspects it covers, in addition to its literature and the representation it represents.
