Discourse within a sentence: An exploration of postpositions in Japanese as an interactional resource

This study explores a phenomenon in Japanese conversation that might be regarded as "discourse-within-a-sentence," or interpolating a sequence of talk during ongoing sentence construction. It explicates the way in which Japanese speakers use postpositional particles as a resource to incorporate an element in a parenthetical sequence into the syntax of a sentence-in-progress. It is shown that the usability of postpositions for achieving discourse-within-a-sentence comes from the situated workings of post-positions used in a wider range of interactional contexts. Through a detailed examination of relevant instances from transcribed Japanese conversations, this study addresses such issues as (i) "sentences" in interaction as both a resource for, and an outcome of, intricate interactional work; (ii) postpositions as resources for retroactive transformations of turn-shapes in Japanese; and (iii) the relationship between typological features of the grammar of a language and forms of interactional practices.
