Using the methodology of Conversation Analysis (or CA), this study examines three types of other-initiated repair initiators (henceforth OIs) that repeats some element in the trouble-source (henceforth repeats) in Chinese conversation: repeats suffixed with question particles ma (?), repeats suffixed with question particles a (?), and question-intonated repeats. It attempts to explore the differences between these typical formats, in terms of their forms/functions and the epistemic stance of the speaker who initiates repair. The main research findings indicate that question-intonated repeat implements an understanding check while repeat suffixed with question particles (ma or a) tends to serve different functions, in that, ma-suffixed repeat is inquiry-implicated while a-suffixed repeat contributes to constructing surprise, (dis)agreement or (dis)belief.
