“禁忌” （taboo），汤加语的意思是“对神圣或邪恶事物的避忌”，汉语译为“塔布”。在人们的日常生活里，由于社会习惯、信仰等原因，在某种特定场合，忌讳使用某种特定的语言或文字，我们把这样被禁忌的语言或文字称为禁忌语。禁忌语是一个较为复杂的问题，它既是普通的语言现象，也是普遍的文化现象。它属于文化语言学范畴内的一个跨多学科领域的课题，主要包括词汇学、词源学、语义学、修辞学，还涉及到历史学、民俗学等多个相关学科。这些特点一方面显示了研究的重要性，另一方面也给研究带来了极大的困难。 本文主要从语言学、文化学的角度，归纳和分析了中、日、韩禁忌语。通过集中介绍中、日、韩，三国禁忌语的类型、表达方式、使用情况，探讨其禁忌习俗，进而考察其文化底蕴。 本文共七个章。第一章是绪论部分，主要阐述了研究目的、研究现状和研究方法。第二章界定对禁忌、禁忌语的概念，进而分析了禁忌、禁忌语发生的原因。第三、第四、第五章分别对中国、日本、韩国的禁忌语，根据禁忌的内容进行分类，整理归纳禁忌语的表达形式。第六章通过对中、日、韩，三国禁忌语的产生原因、对象、表达形式的对比，分析中、日、韩，三国的禁忌习俗的不同点。第七章是结论部分。 通过分析得知，尽管不同时代的语言禁忌各有差异，甚至是天壤之别，但究其产生原因，却大同小异。中、日、韩，三国同属汉字文化圈，受到儒家传统伦理道德和佛教思想的熏陶，三国的禁忌语文化颇有相似之处。但由于各国的文化背景不同，民族不同，也显示出不同点。中国地大物博，历史悠久，独立的大陆文化创造出丰富多彩的禁忌语和禁忌习俗。日本受大和文化的影响，注重和谐，这种文化特征体现在禁忌语中。韩国属于周边文化圈，善于吸收外来文化，特别是大陆文化和西洋文化，由此韩国禁忌语的表达形式非常丰富。

The three countries of China, Japan and the South Korea belong to the cultural circle of chinese character, getting edified from traditional theoretical morality of Confucianism and thought of Buddhism, so the culture of taboo words from the three countries have considerable similarities.
