The purpose of this study is to compare implicit strategies in informal request speech acts between Korean native speaker(KNS) and Chinese Korean learners(CKL). The research questions are (i) In informal request speech acts, what strategies do CKL prefer? (ii) In informal request speech acts, are the use of implicit strategies different in CKL and KNS depending on the request situation? The data was analyzed using chi-squared test. The analysis revealed CKL are generally less likely to use implict strategies than KNS. In addition, KNS chose the strategies in consideration of social strength, intimacy, and listener’s burden as well as the speaker’s own burden, but CKL preferred the strategy directly regardless of the speaker’s own burden in each situation. The study confirmed that there is the difference in strategy choices between CKL and KNS. (Ewha Womans University·Pusan National University)
