Starting off based on some grammar notions found very often in the works of Jacques Lacan (like negation's and verbal tenses' usage), the author brings up the relationship between the language and the unconscious' structure. Revisiting the theoretical antecedents of the Lacanian reflection, this text points to the double facet of Lacan's aim: on the one hand, he binds close together some particularities between the concepts of unconscious and language, whose operations reveal important issues concerning the former, and, on the other hand, he tries to avoid the traditional linguistic perception of those concepts, claiming to have them replaced by his own re-creations.
