Abstract This paper attempts to explore and investigate the role of discourse markers (DMs) in the annexes of the International Civil Aviation Organization (ICAO). Discourse markers are cohesive markers that play an important role in connecting paragraphs, sentences, clauses and phrases to both previous and following items and therefore reflect the speaker’s/writer’s intended attitude about a certain issue. Several studies were made concerning the realisation of discourse markers in different genres, but as far as the researcher knows no study was considered in terms of the International Civil Aviation legal documents such as the ICAO annexes. Thus, the focus of this study is on examining discourse markers in the selected data in terms of function and usage by adopting Hyland and Tse’s classification of discourse markers. The results reveal that the textual function of discourse markers dominates the ICAO annexes, whereas the interpersonal functions were not found. Such results proved the significance of the choice and usage of discourse markers in such a specific register as the legal documents of ICAO which designated the impact they have on the structure and organisation of the texts.

调查国际民用航空组织附件中的话语标记

摘要本文试图探讨和探讨话语标记（DM）在国际民航组织（ICAO）附件中的作用。话语标记是衔接标记，在将段落，句子，从句和短语与之前和之后的项目联系在一起时发挥着重要作用，因此反映了说话者/作者对某个问题的预期态度。关于实现不同体裁的话语标记进行了数项研究，但据研究人员所知，尚未根据国际民航法律文件（如国际民航组织的附件）考虑进行任何研究。因此，本研究的重点是通过采用Hyland和Tse的话语标记分类法，从功能和使用角度检查所选数据中的话语标记。结果表明，话语标记的文字功能在国际民航组织的附件中占主导地位，而人际交往功能却未找到。这样的结果证明了在诸如国际民航组织法律文件之类的特定登记簿中选择和使用话语标记的重要性，指出了语篇标记对文本结构和组织的影响。
