The purpose of this study is to clarify the function and usages of TO which appears at the end of sentences in speech. Sentences that end with quotation marker TO (hereinafter referred to as TO-end sentences) are classified into four types: (1) pauses between TO and such verbs as "omou," "iu"; (2) abbreviations of "omou," "iu; (3) juxtaposed structures of "TO omou," "TO iu"; and (4) complete sentences plus TO. This study also argues the reason TO-end sentences are used.
