In present-day colloquial Japanese, daro(o)/desho(o) , the conjectural forms of the copulas that are agglutinated to at the right periphery (RP) of the clause, are detached from the clause and are used as the stand-alone confirmation/agreement markers. This paper explores the developmental pathway from the RP daro(o) / desho(o) to the stand-alone discourse-pragmatic items, addressing how they serve “exchange structure” and “action structure”-related functions in Schiffrin’s (1987) model of discourse coherence. Evidence from corpus studies of these items in the early 1900s and in present-day Japanese suggest that the stand-alone uses developed from their uses at the RP through the anaphor. This paper provides further evidence for Onodera’s (2014, and elsewhere) suggestion that discourse-pragmatic items tend to be recruited from the RP items in the history of Japanese.

日文RP之外的确认/同意标记的发展

在当今口语化的日语中，daro(o)/desho(o) 是在从句的右边缘 (RP) 上粘连的联结词的推测形式，从从句中分离出来并用作支架 -单独的确认/协议标记。本文探讨了从 RP daro(o) / desho(o) 到独立的话语语用项目的发展路径，探讨了它们如何在 Schiffrin (1987) 模型中提供“交换结构”和“动作结构”相关功能话语的连贯性。1900 年代早期和现代日语中对这些项目的语料库研究的证据表明，独立使用是从它们在 RP 中通过回喻的使用发展而来的。本文为 Onodera (2014,
