As already noted, there are different theories, concepts, or hypotheses about the origin of the language. Since ancient times, attempts have been made to classify these theories according to one or another feature, opposing them to each other.
Even in ancient philosophy, two main directions were distinguished in resolving the issue of the origin of the language: 1) the theory of the natural, or natural, origin of the language, otherwise, the natural, or natural, theory (the "fusey" theory), which explained the origin of the language in a natural way, "from nature " ("by nature"); 2) the theory of the artificial origin of language, ("Theory of Theseus"), according to which the language was created (by God or people) artificially, "by establishment". Both of these directions in different versions continue to exist and develop throughout the history of the development of scientific and philosophical thought, are explained and commented on by various scientists up to the present.
In modern linguistics, the concept of the natural origin of language is represented by various specific theories, or hypotheses. The most famous are such natural theories of the origin of the language as the theory of onomatopoeia, interjections, labor cries, gestures, labor. All of them, in contrast to theories of the artificial creation of a language, consider the emergence of a human language as a long process of its gradual formation on the basis of pre-linguistic means of communication, associated with the adaptation of certain parts of the human body to pronounce speech sounds, with the formation of the speech apparatus.
According to some scientists, almost all the points of view known to us on the origin of the language were known in ancient philosophy; subsequently they were improved in one way or another, "mainly deepened and combined." In modern linguistics, theories of the natural origin of language are more popular, so it is logical to start a review of existing concepts with a consideration of these theories.
