本文通过与「だろぅ」进行比较的方式考察了「ょね」在会话中的使用情况和其“确认用法”语义特征。在概观先行研究后,首先,用具体数据展示了会话中各表现形式的使用情况。然后,以先行研究对「だろぅ」的语义分类为基础,从信息量这一角度对会话中出现的「だろぅ」和「ょね」重新进行了分类整理。最后,运用Brown & Levinson(1987)的“礼貌理论”对会话中「ょね」的多用、「だろぅ」的少用现象进行解释。 By comparing with “ろ ろ ぅ”, this article examines the use of “ょ ね” in conversation and its “Use of Confirmation” semantic features. After an overview of prior research, first, the use of concrete data to demonstrate the use of the various forms of conversation. Then, based on the semantic classification of “だ ろ ぅ” in the first study, this paper re-classifies “ろ ろ ぅ” and “ょ ね” which appear in the conversation from the perspective of information volume. Finally, we use the “politeness theory” of Brown & Levinson (1987) to explain the uselessness of “ょ ね” in conversations and the lack of use of “だ ろ ぅ”.
