Discourse analysis is a broad field that not only studies language use 'beyond the sentence boundary', but also prefers to analyze 'naturally occurring' language use in real-time interaction.Discourse analysis has been taken up in a variety of social science disciplines, including linguistics, education, sociology,interactional socioloinguistics, cognitive psychology,cultural studies,communication studies, etc, each of which is subject to its own assumptions, dimensions of analysis, and methodologies.
Today, the focus on 'cultural' has shifted to 'inter' in "interculturalism" which involves moving beyond mere passive acceptance of a multicultural fact of multiple cultures effectively existing in a society and instead promotes dialogue and interaction between cultures.
