This paper deals with false friends-the source of their sound image (signifiant) is the same, but the concept image (signifie) is differentfound in Korean and Chinese. It is well-known that these false friends frequently cause negative transfer. I demonstrate that the false friends between Korean and Chinese can be classified into four types: ① no semantic resemblance type, ② partially overlapping type, ③ semantic inclusion type I (Korean over Chinese), and ④ semantic inclusion type II (Chinese over Korean). The result of the contrastive analysis of each type shows a striking difference. In the actual communications, false friends between these two languages may lead to misunderstanding. In order to prevent negative transfer due to false friends, students are advised to carefully check the differences in meaning and function.
