Language is the basis of human communication and is the most important key to complete mental development and thinking. Therefore, children must learn to communicate using appropriate language. For this to happen, the development of language in the child must be understood as a biological process, complete with internal laws and with marked stages of evolution. Despite the research that has been conducted, the origin of language is not clearly understood. Language is the faculty that human beings use to communicate with other people through a system of linguistic signs. It is the product of integration of various semantic, morphosyntactic, and phonological components. [For the complete Volume 22 proceedings, see ED656158.]
