This chapter looks at how sexuality, including sexual identity, has been addressed in critical discourse studies. It will first review previous work (e.g., Marko 2008; Morrish and Sauntson 2011) and point out the relative lack of relevant studies in this area, given that research into language and sexuality is mostly indebted to anthropology, sociolinguistics, and conversation analysis. Building on queer discourse studies (Motschenbacher and Stegu 2013), the chapter suggests a way of critically analyzing discourses on sexuality, where discourse is defined as textually mediated social action, with text producers utilizing linguistic resources and sociocognitive representations to establish, maintain, or challenge power relations. Critical discourse studies combine the description of linguistic features with their interpretation and explanation in context and ultimately make transparent the way in which language and discourse either construct and reinforce, or challenge and subvert, normativity. The chapter closes with an illustrative example of the discursive construction of lesbian identities.
