This inquiry analyses the discourse construction of the “telaraña” event, an intervention protest which occurred at a regional university in Chile during the student movement in 2016. This article seeks to evidence the different senses acquired by the event in the discourses both in press and social media, and for students, as well as identify the underlying social representations within. The corpus of this work consists of press articles and reports from regional and national newspapers, along with three public statements and forty one tweets. This study was carried out following the French Discourse Analysis theoretical viewpoint (Charaudeau and Maingueneau 2005), along with the social representations theory (Moscovici 1979; Jodelet 1986). The results show the semantic instability of the “teleraña” event, given that different versions of the event’s aim, particularly regarding the identity of the group the intervention was directed towards (masked people, the police or both), circulated in the analysed media. Furthermore, a tendency towards positively perceiving the student responsible for the “telaraña” was observed, which is a novelty among research on the representation of the student movement.
