First steps in the acquisition of language

Since the born, the child comes into contact with the language. At first he is not aware of it, but then realizes his existence and begins to become involved in it. Listen to, and then try to imitate the sounds he heard, with what we are witnessing the beginnings of the acquisition of the language.  Since that time I start the process of acquisition and learning the mother tongue and the language, in general.
The child learns the language in two ways: by imitation and creatively. By imitation comes into contact with different forms of speech. Creativity allows you to make abstraction of the common elements in these talk and, thus, progress in their learning of the language, basically by analogy. By imitation, the child learns words and phrases; Thanks to their creativity, you can get to invent them.
With the complicity of the adult, the child continues learning. Adult brings a number of behaviors that help as: baby language, feedback, and the contribution of the environment.¿In what is the baby language? It is the way of speaking that adopts the adult before a baby. Its features are: slow the phrase emission; use of finished phrases;  simplification lexical, making it dominate the concrete terms: the presence of the subject in sentences, although it is unnecessary; employment of construction in the third person. Intonation, phrases end up in anticipation and the syllables are pronounced separate and Sung. Thus, the adult, especially the mother, but also family members, introduces children to the language.
The feedback is that the adult repeats the correct phrases, as confirming the child either correctly repeats a phrase that the child has constructed evil. Also the feedback occurs when there are expansions and extensions. In the expansions, the adult, to repeat the phrase of the child, added linguistic elements of limited information, such as articles, etc. In the extensions is extended the sentence, adding new semantic elements.
The environmental contribution takes place when the child attends preschool or watch TV. Finally, when it comes to the school, the teachers are added to this influence, as well as adults with which it interacts.
