This work was created as part of the studies of a research entitled “The clinical research in transference”. In this article, we reexamine some of linguistics concepts such as language, tongue, discourse, linguistic sign, significant, among others, and its articulations with de lacanian field in special the the significant logic. We will analyze linguistics references in Saussure, Jakobson and Benvenist’s works, beyond Lacan’texts and contemporaneous readings about the issue aiming to show some matters from the lacanian trajectory since the linguistic influence, but also considering their unique way of apprehending and using such knowledge. We will also present some comments on discordant elements between these two disciplines, which, throughout his teaching, led Lacan to a conceptual separation from linguistics. Such distancing was justified by the idea that psychoanalysis deals with the subject of the unconscious and what lies outside of language, differently from the linguistic that demonstrates the communicative and expressive functions of the language in the conscious mind.
