Discourse is the conversational form in a community of practice. Discourse is of central importance, because in establishing what is acceptable for people to talk about in a community, and how it is acceptable to talk, the conversational form, or discourse, establishes people's relative power positions and therefore who they are and what they do together. Every community of practice is characterized by a dominant discourse, the most acceptable way to converse, which reflects power positions supported by ideologies.
