Les slogans des jeunes dans les marches pour le climat en France (2018-2019) et la construction de l’identité collective

The analysis concerns the construction of collective identity of young people from the climate marches in France in 2018–2019. It focuses on their slogans from the discursive perspective with reference to the concepts of collective ethos (Amossy 2010), ethos said and shown (Maingueneau 2012), hyperenunciator, hyperdyscourse and interdiscursivity. We argue that there are three main dimensions interacting in building up the collective ethos through the slogans: enunciative (the forms of saying and showing the ethos), interdiscursive (the presence of ideas from various discourses on ecology, i.e. the hyperdyscourse) and the third one expressed by hyperenunciator using the social media which play a major role in the construction of the Thesaurus of this community in the sense of Maingueneau (2004).
