This paper seeks to present, discuss, and analyze the differences as well as the similarities between English and Korean. It is generally agreed that the categories of culture differ across different types of societies and cultures. It is also believed that Western culture differs from Eastern culture. So we tend to think that people in a different culture speak differently, eat differently, wear differently, and interact differently from those in another culture. But it is not necessarily and not always true. I prove this by focusing on how people in a different culture speak a different language without knowing that they actually use the same expressions as those in another culture use. I will deal not only with cultural barriers due to the differences between English and Korean but also with how to work out the problems through the similarities between the two languages.
