This study investigates ongoing grammatical and pragmatic changes in the imperative construction bāng wǒ('help me') in contemporary Taiwan Mandarin. Focusing on service-oriented interactions, it examines how this expression is used, reanalyzed, and socially interpreted in naturally occurring discourse. Drawing on empirical observations of authentic interactional data and questionnaire survey results, the study demonstrates that bāng wǒhas increasingly diverged from its literal meaning as a request for assistance and has developed into a conventionalized politeness marker that mitigates imperative force and promotes interactional harmony. In service encounters, bāng wǒis primarily employed to soften direct instructions rather than to solicit actual help. This development is analyzed as a case of pragmaticalization in Mandarin Chinese, illustrating how imperative constructions may acquire discourse-pragmatic functions over time. By situating these findings within broader discussions of politeness theory and grammatical change, the study contributes to our understanding of interactional norms in Taiwan Mandarin. Finally, given the potential for intercultural misinterpretation of this emerging usage, pedagogical implications are discussed for the teaching of Mandarin as a second or foreign language. |
