As if it knows all language is dialgica, it is sociointeracionista, that is, all enunciated is always a statement of a speaker for its interlocutor, then all 11 language is fruit of an event that involves people. It is a social event. It is not a mere individual act, because through what it is statement, the individual if inserts in the society. It is a communicative interaction in the society through the text, therefore also called sociodiscursiva which subentende, that who writes or speaks discloses an intention. As apud Marcuschi says Bakthin But the language is much more of what one system of fonolgicas, syntactic and lexical structures. The language is not at least a structure; it is structuralized simultaneously in some plans, such as the fonolgico, syntactic and the cognitivo, that if they organize in the articulation process. The language is cultural, historical, social and cognitivo a phenomenon that in accordance with varies throughout the time and the falantes: manifest it if in its functioning and is sensible to the context. It is not a monolithic and transparent system, for ' ' fotografar' ' the reality, but is heterogeneous and it always functions situated in the dialgica relation, as Bakhtin teaches (1979).

(MARCUSCHI 2008, P. 240) the text shows, therefore, as a functional language, because it has an action partner-discursiva who acts on the speaker and the interlocutor. Same Marcuschi already said in one of its texts that ' ' the sorts are action sociodiscursivas that act on the world and say the world, constituting it of some forma.' ' Soon, the understanding of the statements not it is exclusive function of a processing of the contained lingusticas structures in them, but it is also partially function of the perception of the situation where the citizen if finds, with who if it communicates, what it knows and what believes that its interlocutor also knows.
