This paper provides an analysis of discourse markers in English(es) spoken by Zanzibaris, using data from sociolinguistic interviews. The focus is on you know and I think. In English as a lingua franca (ELF), both have been shown to be used differently than by ‘native’ speakers, especially marking subjectivity or speaker-centeredness. The data show similarities with ELF communication, that is the markers express subjectivity in highlighting or evaluating part of the discourse, and convey speaker-centeredness as ‘fumbling devices’. Thus, the paper raises the question as to whether these and similar sociolinguistic interviews applied for the documentation of New Englishes should be analyzed as lingua franca communication.

你知道，我认为在桑给巴尔的英语（es）

本文使用社会语言学访谈的数据，分析了桑给巴尔人所说的英语中的话语标记。重点是你知道，我认为。在英语作为通用语言 (ELF) 中，两者的使用方式已被证明与“母语”说话者不同，尤其是标记主观性或以说话者为中心。数据显示与 ELF 交流的相似之处，即标记在突出或评估部分话语时表达主观性，并将以说话者为中心的态度传达为“摸索工具”。因此，本文提出了一个问题，即这些和类似的社会语言学访谈应用于新英语的文献中是否应被分析为通用语言交流。
