This document discusses the field of linguistic anthropology, which examines the relationship between language and culture. It specifically focuses on how language is used and integrated into various cultures around the world. The key topics covered include speech communities, the performing of language through conversation and gestures, language socialization, and the role of power in language. Speech communities are defined as groups that use language to regularly interact and are distinguished from other groups by differences in language usage. Conversation and gestures are important aspects of language performance that vary across cultures. Language socialization looks at how language and culture are acquired over time through social interaction. Finally, language plays a role in constructing power differences between speakers based on cultural ideologies around language.
