From a conversation-analytic perspective, this paper examines various sequential aspects of the use of add-ons in Korean conversation as part of the linguistic practice geared towards organizing affectively loaded social actions. Defiend as a non-main clausal constituent added after a possible point of completion of a turn-constructional unit, add-ons furnish the speaker with the resource for managing the turn-transition space after an affectively-loaded action is pefrormed through an allusively formulated TCU. In many contexts, allusive TCUs that are retroactively elaborated by an add-on serve to highlight the speaker`s affective or collusive stance (rather than the referential meaning) implicated in a variety of affectively loaded actions. with focus being given to presenting the stance-ridden upshot turn-initially and/or increasing contiguity with the prior turn unit. Add-ons. then, are in the service of managing the post-completion space by way of modulating the prior action in the aftermath of the initial display of affect or responsiveness. This and other related sequential features of TCUs with add-ons are examined in the context of topic-elicitation and assessment, with special refernce to the sequence-initiating or terminationg import of add-ons.
