Ethnomethodology is a diversified sociological enterprise that is concerned with the nature of an ‘accomplished’ social order and people’s engagement in that order. With its insistence on the primacy of empirical, situated investigations of social actions, its concern with intersubjectivity and interpersonal meaning, its exhortation that social activities are locally accomplished achievements, and with its abiding interests in linguistic communication, ethnomethodology has important affinities with the encompassing concerns of pragmatics.
