The English discourse marker so can mark result, inference, connection, topic development, action prompting, and emergence of incipiency. In English as a Lingua Franca (ELF) contexts, it also marks hesitation, self-correction, and floor-holding. Our paper uses quantitative and qualitative discourse analytical methodology to examine so in a corpus of video-mediated informal conversations between ELF speakers, where it is the most frequent discourse marker. The analysis demonstrates that all functions documented in first-language English use also occur in ELF. We also document extended uses of so to prompt inference and to illustrate pragmatic competence, particularly in combination with other discourse markers such as okay.

所以在扩大圈子中以视频为媒介的交流中

英语话语标记因此可以标记结果、推理、联系、话题发展、行动提示和开始的出现。在英语作为通用语 (ELF) 语境中，它也标志着犹豫、自我纠正和坚持。我们的论文采用定量和定性的话语分析方法研究，以便在ELF音箱，它是最常见的话语标记之间的视频介导的非正式谈话的语料库。分析表明，所有记录在第一语言英语使用中的功能也出现在 ELF 中。我们还记录了so 的扩展用法，以促进推理和说明语用能力，特别是与其他话语标记（如Ok ）结合使用。
