The word “pragmatic” derives from the Latin expression pragmatikos, which means, among other things, “power to act”, which comes from the “pragma” act. act” (in modern Greek” /Pragma “an object, something that can be perceived by the senses”),  again by the verb “prasss”) “to do, to act, to pass, to exercise, to reach.”  Grammar can be described as a system of categories and a set of rules that determine how categories come together in different aspects of meaning.  Languages differ greatly on whether they are coded by the use of lexical categories or units. However, several categories are so common that they are almost universal. These universal categories include codifying the grammatical relationships of participants and preachers, grammatically distinguishing their relationships with a predicate, coding temporal and spatial relationships on predicates and a system of grammatical persons that govern reference and distinction between spokespeople and recipients and those they speak of.  Languages evolve and diversify over time, and the history of their evolution can be reconstructed by comparing modern languages to determine the characteristics that their genee must have had for later stages of development to occur. A group of languages descended from a common ancestor is called the language family. A language that is proven to have no living or non-living relationship with another language is called linguistic isolation. Languages whose relationships have not been established are not classified. The academic consensus says that between 50% and 90% of the languages spoken at the beginning of the 21st century will probably be extinct by 2100.    Many things are recorded during the first year of life, because brain development accelerates and the senses are focused and arranged. Primary facilitators are almost instinctively encouraged to transmit dialogue skills in babies from birth. As almost everyone who has spent time around a baby at this stage of rapid development can testify, there is a compulsion to interact with the child, which is usually entertaining for adults and babies.
This constraint is not accidental or accidental, and we would be wrong to think that our communication is useless or just for fun. We would also be wrong to think that language learning only begins when a baby says his or her first words. Until then, babies have learned a lot about our verbal patterns of communication and interaction through observation and practice. Among these most important developments are: the languages of the world can be grouped into linguistic families composed of languages that are proven to have common ancestors.
