This study provides an annotation schema of a wide range of enunciative strategies underlying every enunciation process by which an enunciator actualizes a predicative content. We show that most of these enunciative strategies involve the enunciator in a relationship of Engagement (concerned with the notions of truth value and axiological/appreciative value) or Non-Engagement toward a stated predicative content. Our approach takes place in the French enunciative framework rooted in the work of Bally (1932). We explicitly compare our approach with that of Appraisal theory (Martin and White, 2003). We also illustrate the applications of our schema with a manual annotation experiment conducted on a corpus of French history textbooks. This experiment reveals interesting diachronic variations in the enunciator’s modes of Engagement and Non-Engagement.
