Abstract: The evolution of terminology, studied from the point of view of determinologization, based on a diachronic corpus of 1.5 billion words taken from the newspapers The Independent and The Guardian, makes it possible to identify the salient features of this evolution: the coexistence of divergent meanings and uses, primary and secondary determinologization, flexional specificity in the face of lemmatization, the innovative use of specialized and semispecialized terms, as well as the question of grammatical change.
