摘要:This paper discusses the influence of Cláudia de Lemos’s reflection on language and language acquisition for the circumscription of the notion of diagnosis in the field of language/speech therapy. I argue that most speech pathologists who have approached the above mentioned author’s works made such a movement in a naïve and equivocal way. In this article, I endeavor, after the critical review presented, to suggest an alternative proposal for diagnosis that emphasizes my theoretical commitment to a specific language theory which allows for the consideration of pathological/symptomatic speech.
