Structuralism as current of thought, in linguistic research particularly, emerged in the beginning of the 20th century. In Europe, to speak only about this continent, Saussure - cited by Nivette (1974) - became an outstanding figure with his ideas on language as a system. According to Saussure and his followers, language is highly ongoatu. It is a complex structure. The Saussurean school bequeathed us this realistic vision of what is language. Still referring to Nivette, we feel that it is worth poiting out that, after Saussure, there has been a number of researchers who focused on language with rather different views. Among them is Chomsky (1957), who advocates another linguistic trend (of world fame) strongly marked by a particular concern for the abstract dimension of language. Indeed, Chomsky draws the attention of the linguists of his time onto the mental processes behind language (mentalism). This is already a step in the post-structuralist era.
