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

从《日本方言语法图集》中的语言地图看语体系统、意志和推测形式、连接形式的发展[j]。很明显，古代的九种共轭类型在标准日语中变成了今天的五种。但在方言领域，中国地区有6种共轭类型，九州地区有9种。在中国，古老的n不规则型（Na-hen动词）仍被保存下来。在九州的一些地区仍然保留着九种古老的方言，但在其他地区也发现了一些基于方言独特方面的创新。意志和推测形式日本中部有助动词“u/yo-u”，东部有助动词“uzu”和“bei”；另一方面，“-yuu/-yoo”在语言地图的西部地区使用。通过对这些地图和古文献的分析，我们可以看到“北→uzu→-yuu→-yoo→yo-u/u”在意志形式和“beiu→-uze→-yuu→-yoo→yo-u/u→- da/dja/ya+roo”在推测形式上的变化。日本中部有“sakai”和“yotte”形式，东部有“kara”形式；另一方面，“ken/keni/kind”的形式出现在西部地区。通过对这些地图和古文献的分析，我们可以看到“kara”→“ni”→“de”→“yotte”→“sakai”的形式变化。

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"
