The study explores de phenomenon of deception. It proves that lies are communications with fictional content focused on the expectations of a person or social group and aim a problematic situation. The untrue communicative instance lacks figure: nobody is declared a liar when they lie. The productions do not have a producer presenting itself as a liar, but it is always emphasised by a certain recipient. They have a content related to the current cognitive-practical interests of the target. The liar acts in two directions: by distorting a correct thinking, by perverting the language. It is a man lacking language responsibility and a profiteer of cogitation.
