Abstract
Talk constitutes people and situations. People and situation categorizations are related to one another through talk. The resulting systemic categorization is a specific enactment. Members’ categorizations of self, other members, and the situation may be tacit Sacks’ membership categorization devices (MCD) are modified to handle tacit categorizations. A componential approach to members’ categorization of people and situations is refined through the explication of members’ talk. Further explication displays how member constituted people and situation categories interact to accomplish systemically the enactment of returning.
