This document provides an overview of key concepts in discourse analysis. It defines discourse as socially constructed knowledge that represents aspects of reality through language. Discourses are finite sets of ideas that get expressed through different texts. They have histories, social distributions, and can be realized through actions or representations. The document outlines the "anatomy" of a discourse, including the actions, manner, actors, presentation, resources, times, and spaces that make up social practices. It also discusses how realities get transformed and constructed through discourses via processes of exclusion, rearrangement, addition, and substitution. The goal of discourse analysis is to understand how language shapes human experiences and mediates the construction of social realities.
