本論文目的於探討N-ga DEKIRU句構在何種情形下表達＜生起＞、＜完成＞以及＜可能＞中的其中一種語意。至今為止，N-ga DEKIRU被定位於可能表現的一種，而尚未有以N-ga DEKIRU為中心，針對其多義性分析的研究。針對動詞DEKIRU的多義性有所提及的只有針對DEKIRU的歷史上的型態與語意變化的研究以及辭典而已。因此，本論文藉由導入屬性結構（Qualia Structure），論述N-ga DEKIRU動詞句的語意是由名詞N和動詞DEKIRU兩詞組成分經由共構成的過程而衍生。又，本論文不局限於N-ga DEKIRU動詞句，也以句構單位來探討影響句子整體的要素。 　　本論文共7章，首先於序章闡述研究動詞及目的、研究方法與本論文的構成。於第一章，概觀先行研究，指出其問題點，並提出本論文的課題。在第二章，以認知語言學的分析方法探討動詞DEKIRU的多義性，並使用屬性結構探究其語意構造。於第三章，筆者以NINAL-LWP for BCCWJ語料庫收集與N-ga DEKIRU句構中的名詞作為本研究的考察對象，並將之分類為事件名詞（event noun）以及實體名詞（entity noun）。於第四章，筆者推論N-ga DEKIRU動詞句的語意是經由名詞與動詞兩者共構成而衍生，並探討共構成時所使用的類型強制的適用條件。最後於第五章，筆者以句構單位探討第四章所無法解決的多義性的問題。第六章為結論。 　　經由以上論述得到結論為，N-ga DEKIRU句構的語意，有取決於名詞的情形，也有在以N-ga DEKIRU動詞句單位時擁有兩義性的情形，而後者的語義又受附加部的有無、否定接詞nai以及時態等影響。 / The purpose of this study is to examine which meaning amoung OCCURENCE, PERFECTIVE, and POTENTIALITY is represented in case of ‘N-ga DEKIRU’ construction. In conventional research, ‘N-ga DEKIRU’ has been regarded as one of the potential expressions, but as for its polesemy, it has barely been studied yet. There is only one research focusing on the morphological and semantic change of the verb ‘DEKIRU’, and its polysemy is only mentioned in dictionaries. Accordingly, Qualia Structure is introduced into the study of N-ga DEKIRU construction to show that the meaning of N-ga DEKIRU is generated by means of the process of co-composition from its constituents, N and DEKIRU. Furthermore, I also investigate what elements affect the meaning of the whole sentence at the syntactic level. This thesis consists of 7 chapters. In the introduction, I describe the motivation and purpose of this work. In chapter 1, I point out the problems after reviewing the previous research, and present the subjects of this paper. In chapter 2, I examine the syntactical behaviors of the verb ‘DEKIRU’; meanwhile, I analyze its polysemy through cognitive linguistic approach, and stipulate its semantic structure. In chapter 3, I collect the nouns co-occuring with DEKIRU from the corpus named NINJAL-LWP for BCCWJ, and categorize them into event nouns and entity nouns. In chapter 4, I assume the meaning of the verb phrase ‘N-ga DEKIRU’ to be generated by the process of co-composition, and explore the condition of type coercion which is applied in the process of co-composition. In chapter 5, I examine the unsolved problems in previous chapters at the syntatic level. Finally, in chapter 6 comes the conclusion. From the above, the conclusion is that in some cases, the meaning of N-ga DEKIRU construction is determined by the nouns; whereas there are cases that the verb phrase ‘N-ga DEKIRU’ still represents two meanings. As for the latter case, adjuncts, negation, tense and aspects are the elements affecting the meaning of N-ga DEKIRU construction.
