The Process of Diachronic Change of Quotative Particles and Formal Nouns in Japanese : Grammaticalization, Subjectification and Lntersubjectification

本研究的目的是考察在会话语言(包括反映当时会话语言的旧文本)中频繁出现的语素的历时变化过程，同时参考“语法化”、“主观化”和“主体间化”的概念。分析的主要对象包括引语助词(尤其是tte)和形式名词(尤其是wake)。我调查了意义、功能和周围结构是如何发生变化的，同时也提出了关于这些变化的原因和方向的想法。历时数据包括从江户时代到今天的日语会话语言的记录，这些记号根据时间段进行分组。这项授权使我能够创建一个数据库，其中包含关于所有标记的形态和结构环境、语义和话语功能的信息。此外，我还用英语和日语在日本和海外的会议和期刊上介绍了研究结果。国际语用学会议(2005年在意大利，2007年在瑞典)上的两个小组讨论特别重要，因为我能够作为共同组织者和演讲者做出贡献。在这里，以及在许多其他会议上，我通过与擅长各种语言和主题的学者的互动，获得了有用的反馈。2005年专家小组的结论以一本书的形式发表(《历史语用学杂志》，8.2期)，我是这本书的联合编辑和撰稿人。来自2007年专题小组的论文将以丛书的形式出版，名为《语篇和语法研究》(John Benjamins出版公司)。我已经开始担任本书的撰稿人和联合编辑。

The goal of this study was to investigate the process of diachronic change of morphemes which frequently occur in conversational language (including old texts reflecting conversational language of that time), while referring to the concepts of "grammaticalization," "subjectification" and "intersubjectification. " The main target of analysis includes quotative particles (especially tte) and formal nouns (especially wake). I investigated how changes in meaning, function, and surrounding constructions occurred, while also presenting thoughts about the reasons and directions of these changes. The diachronic data includes the documentations of conversational language from the Edo period through present-day Japanese, with the tokens grouped according to time periods. This grant enabled me to create a database, containing information on morphological and structural environments and semantics and discourse functions of all the tokens. Furthermore, I presented the results in conferences and journals, both in Japan and overseas, in English and Japanese. Two panels at the International Pragmatics Conference (Italy in 2005, Sweden in 2007) were especially significant since I was able to make contributions both as a co-organizer and speaker. Here, as well as at many other conferences, I obtained useful feedback through interactions with scholars specializing in a variety of languages and themes. The conclusions of the 2005 panel have been published in the form of a book (Special issue of Journal of Historical Pragmatics, 8.2), for which I acted as a co-editor and also a contributor. The papers from the 2007 panel are going to be published as a volume in a series called Studies in Discourse and Grammar (John Benjamins Publishing Company). I have started working as a contributor, as well as co-editor, for this volume.
