In doing so, many relationships of CDA to other components such as social structure, social event, social practice, and orders of discourse are introduced in such ways that grant redefinitions to discourse and discourse analysis as well as show why CDA is critical and how its constructing components (critical, discourse, and analysis) draw its meaning and contribute to form its aims and principles.
