Recently, the traditional terminology conception has changed due to the irruption of new approaches from the so-called Cognitive Sciences, particularly from Linguistics, Psychology and Philosophy. These new approaches allow the presentation of a more adequate explanation of the use and function of concepts in a very diverse communicative functions, which were not taken into account by General Theory of Terminology. Moreover, from this cognitive point of view, it is possible to describe specialised knowledge acquisition, categorisation and production processes. For this reason, the aim of this paper is to integrate these new ideas into a comprehensive theory of terminology.
