全国方言地図と文献との対照による助詞・助動詞の発達・伝播に関する研究

通过分析《日本方言语法地图集》中的语言地图，研究连词系统、意志和推测形式以及连词形式的发展1。连词系统研究在标准日语中，由古代的九种连词系统演变为现在的五种连词系统。但在方言领域，中国地区有六种连接类型，九州地区有九种。在中国，古老的N-不规则类型（Na-hen动词）仍然保留。在九州，九种古老的方言在某些地区仍然保留着，但在其他地区也发现了一些基于方言独特方面的创新。2.意志和推测形式在中央日本有助动词“u/yo-u”，在东部地区有“uzu”和“bei”;另一方面，在语言地图的西部地区有“-yuu/-yoo”。通过对这些地图和旧文献的分析，可以看出，在意志形式上，“bei→ uzu →-yuu→-yoo→yo-u/u”的形式发生了变化;在意志形式上，“beiu→ -uze →-yuu→-yoo→yo-u/u→--da/dja/ya+roo”的形式发生了变化。表示理由的连接形式在日本中部有“sakai”和“yotte”形式，在东部有“kara”形式;另一方面，在西部地区有“ken/keni/kind”形式。通过对这些地图和旧文献的分析，可以看出“卡拉”→“你”→“得”→ "约特”→“酒井”的形式发生了变化

Study of Development of Conjugational Systems, Volitional and Conjectural Forms, and Conjunctive Forms by analyzing Language Maps in the Grammar Atlas Of Japanese Dialect1. Study of Conjugational SystemsIt is clear that the nine conjugational types in ancient time changed to five today in standard Japanese. But in the field of dialects, there are six conjugational types in the Chugoku area and nine in the Kyusyu Area. In Chugoku old N-irregular type (Na-hen verb) is still preserved. In Kyusyu the nine ancient types are still preserved in some districts, but some innovations based on unique aspects of the dialects are found in other districts.2. Volitional and Conjectural FormsThere are auxiliary verbs "u/yo-u" in the cental Japan and "uzu" and "bei" in eastern parts ; on the other hand, "-yuu/-yoo" are used in the western areas of the language maps. Based on an analysis of those maps and old literatures, one can see a change n the form of "bei→ uzu →-yuu→-yoo→yo-u/u in volitional forms, and "beiu→ -uze →-yuu→-yoo→yo-u/u→--da/dja/ya+roo" in conjectural forms.3. Conjunctive Forms Expressing ReasonThere are "sakai" and "yotte" forms in the central Japan and "kara" in the east ; on the other hand, "ken/keni/kind" forms are found in the western areas. Based on an analysis of those maps and old literatures, one can see a change in the form of "kara" → "ni" → "de" →yotte" → "sakai"
