Politeness theory grew out of the emergent traditions of pragmatics and interactional sociolinguistics in the 1970s. It was not, however, until the 1980s and 1990s that research and development of politeness from an academic perspective really blossomed. Linguistic‐politeness researchers are interested in how participants create, maintain, or repair positive social, and hence effective interpersonal relationships within and through linguistic interaction, in a range of sociologically or pragmatically understood settings. This article provides an historical account of politeness theory, showing how each new theoretical formulation led to a critique that, in turn, generated a new family of politeness theorizing.
