Abstract:
The concept of interdisciplinarity appeared initially quite poorly defined, even if it is based on the unification of the science. The paper has as main objective to clarifying the terms of multidisciplinarity, interdisciplinarity and transdisciplinarity, to indicate the scientists who worked and succeded in the field of the multidisciplinarity, interdisciplinarity and transdisciplinarity research and to sketch an unitary and interdisciplnar view of the discipline Language and Communication.
