佛教对中国文化的影响是长久的、全方位的，据考察，不少佛经中的词语演变为了汉语的成语，这是佛教在语言方面影响的体现。现代汉语中有许多使用频率很高的成语均来源于佛教。本文从中选取了五个成语：不可思议、不知不觉、一心一意、皆大欢喜、五体投地，考察其语义及文化内涵。本文通过研究发现，这些成语在佛教中有着特殊的含义，与现代汉语的语义有很大差别：“不可思议”有“非常人的思维能力所及”和“非思维所行境界”的语义；“不知不觉”有“不了知、不了悟”、“不能以无分别智了达诸法自性”、“没有察觉到”的语义；“一心一意”有“使心理安住”或“同心”的语义；“皆大欢喜”有“都产生特别强烈的欢喜之心”的语义。同时，在文化内涵方面，这些成语带有明显的佛教思维方式，体现了佛教文化的特点，如“五体投地”和“一心一意”可以作为积集福德资粮的一种方法。

According to this semantic and cultural connotations study, there are lots of Buddhist translated words that transformed into Chinese idioms. This phenomenon reflects the influence of Buddhism on Chinese language. In modern Chinese, there are lots of high frequency idioms originated from Buddhism, such as “bukesiyi”, “buzhibujue”, “yixinyiyi”. This means that the idioms play an important role in modern Chinese. This study selected five idioms which originated from Buddhism, for example “bukesiyi”, “buzhibujue”, “yixinyiyi”, “jiedahuanxi” and “wutitoudi” to study their semantic and cultural connotations. This research found that these idioms have their own meaning and connotations in Buddhist scriptures which differentiated from modern Chinese. The first word “bukesiyi” has meaning of “the state that people’s mental power cannot reach”, or “non thinking state of mind” which related to Sunyata；the second word “buzhibujue” has meaning of “unrealize”, “cannot realize the true dharma”, and “being unaware”. The third word “yixinyiyi” has meaning of “samadhi” or “with one heart”. The fourth word “jiedahuanxi” has meaning of “being strongly joyful”. “wutitoudi” which is the last word has connotations of “collecting merits” .
