日本語終助詞「よ」と台湾華語語気助詞「喔」の 対照研究 ―「情報のなわ張り理論」の観点から ―

Abstract

本研究旨在探討日語終助詞「よ」與台灣華語語氣助詞「喔」的對應關係，針對日語教材及台灣華語教材進行了量化與質性分析。 在日語教材中，從量化分析結果顯示，對應「よ」的語氣助詞以「喔」出現頻率最高；此外，針對被歸類為「無對應」的用例進行分析後，結果顯示其中大多數例子即使加上「喔」也可成立。此結果進一步證實了「よ」與「喔」之間具有密切的對應關係。質性分析應用了神尾（2002）的「情報のなわ張り理論」，確認「よ」對應選用「喔」的場景為聽者情報值極低的情況；反之，情報值不確定或非極低時，傾向選擇「喔」以外的語氣助詞。 在台灣華語教材的分析中，對應「喔」的日語終助詞以「よ」出現頻率最高，因此從雙向確認了兩者的對應關係。另一方面，「ね」作為對應語出現時，在說話者與聽者共享同等情報的文脈中，使共感或同意功能前景化。因此，「喔」雖與「よ」強烈對應，但某些情況下與「ね」功能部分重疊。 最後，本研究補充分析「ね」與「喔」的對應關係，結果顯示在特定文脈（如感想・評價、請求・指示、行動報告・意圖、注意・安全喚起）中，「ね」與「喔」可對應使用。此外，本研究結果顯示情報結構與對人際關係的顧慮會獨立影響終助詞選擇。特別是「よ」適用的場景中選用「ね」的例子，顯示了發話中對人際關係的顧慮具有優先性。這揭示了終助詞研究需納入語用論分析的面向，而非僅限情報結構分析的重要性。

This study investigates the correspondence between the Japanese sentence-final particle ‘yo’ and the Taiwanese Mandarin modal particle ‘o’ through quantitative and qualitative analyses of Japanese and Taiwanese Mandarin textbooks. The quantitative analysis shows that in Japanese textbooks, ‘o’ appears most frequently as the modal particle corresponding to ‘yo’, indicating a high degree of correspondence between the two. Furthermore, an analysis of cases classified as having “no correspondence” reveals that in most instances, ‘o’ can be contextually supplemented. This further supports the strong correspondence between ‘yo’ and ‘o’. The qualitative analysis, based on Kamio’s (2002) Theory of Territory of Information, indicates that ‘o’ is selected in contexts when the listener’s information state is extremely low. In contrast, when the listener’s information state is uncertain or not extremely low, other modal particles besides ‘o’ tend to be selected. The analysis of Taiwanese Mandarin textbooks confirms that ‘yo’ appears most frequently as the sentence-final particle corresponding to ‘o’, thereby demonstrating a bidirectional correspondence between the two forms. In cases where ‘ne’ appears as a corresponding form, the context involves shared information between the speaker and the listener, with empathetic and agreement-related functions being foregrounded. This suggests that while ‘o’ strongly corresponds to ‘yo’, it partially overlaps with ‘ne’ depending on the certain context. Finally, a supplementary analysis of the correspondence between ‘ne’ and ‘o’ suggests that information structure and politeness strategies independently influence sentence-final particle selection. In particular, the cases in which ‘ne’ is selected even in contexts where ‘yo’ would be expected indicate the priority of politeness strategies in actual discourse. These findings highlight the importance of incorporating not only information structure but also sociopragmatic perspectives in the study of sentence-final/modal particles.
