動詞sitagau，tomonau之語法化

Grammaticalization of the Japanese Verbs: Sitagau and Tomonau

本論文探究日語動詞sitagau，tomonau之語法化特徵。考察結果顯示兩語之統語變化，語意變化過程中，泛化（Generalization），類變（Decategorialization），層次（Layering），持續（Persistence）之四機制牽涉其中。而兩語語法化後之複合助詞nisitagatte，nitomonatte中亦可見古語及現代日語之語法特徵並存。相較兩語語法化歷程時可見，sitagau原具之空間位置變化之意演變為表具時間幅度之事態間之變化，而tomonau原具有共處物理空間之意則演變為表共有時間之事態間變化之意。<

On the other hand, the meaning of sharing the space changes into the meaning of sharing time when tomonau changes into nitomonatte.
