The purpose of this study is to investigate the influence which thought and culture have on languages. Languages have reflected thought and culture of its users. In order to accomplish this purpose, I will compare two languages-Korean and English: the former is affected by oriental thought and culture, and the latter is influenced by occidental thought and culture. Following the introduction, in chapter 2, I divide respectively Korean and English into a situation-centered language and a structure-centered language and look into the difference between Korean and English. Chapter 3 deals with the difference between a predicate-centered language, Korean and a subject-centered language, English. A situation-centered language, Korean often leaves out subject or object, therefore Korean is a predicate-centered language. On the other hand, a structure-centered language, English has an emphasis on the structure of sentences. As English usually locate the subject at the front part of sentences, it is a subject-centered language. In chapter 4, Korean and English are divided into a synthetic language and an analytic language. `The Synthetic language and the analytic language are different in the use of articles, concept of single/plulral, word order and connection of word-word/phrase-phrase/sentence-sentence. This study is summarized and concluded in chapter 5 as follows. In learning a foreign language, it is more effective and efficient to compare culture and thought of learners with those of foreign-language speakers.
