:Occasioned Semantics: Meaning in Verbal Interaction:Occasioned semantics refers to the study of the constraints on, and rhetorical and sequential consequences of, the use of expressions in actual occasions of verbal interaction.  It deals with the organized fields of meaning that are constructed in conversational exchange.  Membership categorization analysis and sequential analysis, as well as certain developments in ethnosemantics and linguistic pragmatics, provide the starting points for an occasioned semantics.  It poses, at least, the following questions: What are the contextual constraints on occurrence of particular expressions on a given occasion?  What are the intelligible, relevant, plausible, contextually appropriate alternatives?  What structured relations hold among expressions used in a spate of talk?  What are the sequential implications of these structures?  What are the rhetorical uses, including implication and implicature, of particular expressions on particular occasions?  These questions, of course, are not independent.
