In second language acquisition (SLA) studies, there has been much research that has dealt with the negotiation of meaning in conversation as a way of characterizing the nature of non-native speakers. This study attempts to explore the next-turn repair initiators (NTRIs) that function as questions to negotiate meaning in English conversation between non-native speakers whose native language is Korean. NTRIs are not only question types to negotiate meaning, but also initiate the repair organization in sequential and interactional contexts. Concerning the types of NTRIs in English conversation, NTRIs between Korean speakers (KSs) are frequently used in the following question types (ⅰ) what, huh, or yeah, (ⅱ) echo question with partial or full repetition of the previous turn, (ⅲ) appender question with candidate information. This study also shows that NTRIs perform the following functions: (ⅰ) requesting for repetition of the entire trouble-source (TS) turn, (ⅱ) seeking confirmation from the previous speaker with the partial or full repetition of the prior turn, (ⅲ) collaborating to manage conversation. Finally, this study of NTRIs suggest the need to explore the interaction between non-native speakers in pedagogical implications.
