ABSTRACT
The simple elocution includes the four types of double structure: quoted discourse, autonomous form of discourse, proper name and shifters, that is, the pronoun of the first person and the perfect tense that indicates an event prior to the transmission of the message. In language and its use, duplicity carries out a basic function. If J. Lacan states that "desire is articulated, but it is not articulable", he does it precisely based on these relations among need-demand-desire. Lacan believes that a trace, a mark of the subject of the unconscious, can be localized in the structure of language. The remainder between need and demand implies already the articulation of a chain of the other, for instance, the 'first said'; but it will not be articulable because it is precisely that of the need which does not pass into the demand.
