This paper is about the importance of interdisciplinarity in the process of foreign language teaching and learning at the Faculty of Foreign Languages and Literatures of the “Ion Creangă” State Pedagogical University. This process is being analyzed with the purpose of showing its direct role in developing linguistic competences in students, in order to attain linguistic performance, according to the generative grammar concept by Chomsky. A distinction will be made among the concepts of interdisciplinarity, multidisciplinarity, pluridisciplinarity, and transdisciplinarity. The internal and external interdisciplinary relationships will be shown, as well as the orientations of their practical application: textual and auditory. The large spectrum of theoretical and practical disciplines that are taught at the Faculty will be reviewed, along with their interdisciplinary connections, with a special emphasis on the value of the university research papers.
