This paper aims to survey how the defectors are adapting to the linguistic environment in South Korea. As the number of defectors increase rapidly in recent years, there are many social discord in South Korea. Furthermore it contains many linguistic complications. Under the existing condition, this survey is hoped to find the way to decrease the linguistic complications in reunion period of Korea. Most of the defectors have been experienced the difference of language between South and North Korea. This difference makes it difficult for them to settle down in the South Korea. But they are easily adapted to basic words of Korean society. It is hard for them to adapt to many new words which are derived from ideological struggle and social organization, the words which written in chinese characters, english, many loan words, and different pronounciations and intonations. But they make an effort to adjust themselves to linguistic society of South Korea. As a result we find out that the persons who are well adapted to social environment also adapt to linguistic environment.
