ethnomethodology and conversational analysis

in a speech community, people utilize their communicative competence which they have acquired from their society as part of their distinctive sociolinguistic identity. they negotiate and share meanings, because they have commonsense knowledge about the world, and have universal practical reasoning. their commonsense knowledge is embodied in their language. thus, not only does social life depends on language, but language defines social reality. with practical reasoning, people in a speech community use, appropriately, their commonsense knowledge in different social settings in order to negotiate suprasentential meanings. all of this knowledge is acquired without overt, explicit and intentional training. proceeding along linguistic ethnography and functional lines, we may attempt to specify just what it means to be a truly successful and competent speaker of a particular language within the framework of a speech community.
