Abstract

The article considers the contextual relationships and the semantic variation of 5 lemmata belonging to the semantic field of 'power'. It aims to demonstrate how their use in a diachronic corpus of U.S. Presidential speeches testifies to the development of the relationships between the executive, legislative and judicial branches of government. Furthermore, it shows how this is to relate to the emergence of a new conception of a new conception of the Presidency, one with a specific rhetorical focus and an attention to the persuasive effects of its communication strategies. The use of the 5 lemmata shows how, during the 20th century, two strategies for the contruction of consensus around the Presidency have developed.
