The COVID pandemic has sparked fear among many people worldwide and has thus led to the emergence of a variety of conspiracy theories. Individuals believing in these theories come from various social and demographic backgrounds, some of them being mere skeptics, while others are more radical and extreme. The present paper investigates the use of language in a conspiratorial anti-COVID Facebook group with the aim of describing the linguistic features and strategies employed to share and spread conspiracy theories and to (...) form a common identity. The results show that the group uses features typical of extremist groups, such the ideological in- and out-group presentation, the use of agentless passives to create fear, and intertextual references. Further strategies detected in the data are the misrepresentation of scientific knowledge, the use of colloquial language, humor, and irony, among others, which are used to create a bond among the groups’ members and to set themselves apart from the government and the rest of the population, whom they perceive as enemies and oppressors.
