Sequencing in Conversational Openings1

An attempt is made to ascertain rules for the sequencing of a limited part of natural conversation and to determine some properties and empirical consequences of the operation of those rules. Two formulations of conversational openings are suggested and the properties “nonterminality” and “conditional relevance” are developed to explicate the operation of one of them and to suggest some of its interactional consequences. Some discussion is offered of the fit between the sequencing structure and the tasks of conversational openings.
