In this article, I examine the role of talk in constructing speakers as heterosexual beings. Heterosexuality is a cultural construction relying on strictly enforced norms for its continuing dominance. Queer linguistics initially focused on the language of lesbian, gay, bisexual and transgender (LGBT) groups, but is now widening its focus to explore the discursive construction of heterosexuality, and to show that language does not just reflect the heteronormative order; it is also involved in reproducing that order. I shall explore how heterosexuality is ‘done’ in everyday talk, drawing on Cameron and Kulick’s idea of ‘the heteronormative hierarchy’. I shall also show how closely sexuality and gender are linked, and will argue that this closeness is essential to the maintenance of heteronormativity.
