Interactional sociolinguistics
Interactional sociolinguistics is a subdiscipline of linguistics that uses discourse analysis to study how language users create meaning via social interaction. It is one of the ways in which linguists look at the intersections of human language and human society; other subfields that take this perspective are language planning, minority language studies, quantitative sociolinguistics, and sociohistorical linguistics, among others.
