This chapter provides a selective overview of some of the most relevant aspects of intergroup communication. We first introduce the topic by discussing the relationship between intergroup communication and social identity. In the second part, we then cover three language strategies (category labels, language abstraction, and metaphors) that different groups can adopt when communicating between and about groups. Category labels reveal social meaning well beyond mere classification, by triggering affective reactions and stereotyping, whereas language abstraction and metaphors play a central role in establishing and maintaining stereotypes and intergroup relationships. In the third part, we directly address specific social groups, including salient and relatively unambiguous social categories (i.e., gender and race) as well as more fluid categories (i.e., regional and social background as well as sexual orientation). The chapter provides a broad overview of linguistic strategies and of their specific use with selected social categories, together with suggestions for the development of future research and theorizing.
