Nominalization refers to the process in which verbs, adjectives and phrases that act as nouns in sentence. The ways of actualizing nominalization are different in Chinese and Korean. Compared with Chinese, Korean is able to actualize nominalization more freely. Therefore, in the process of translation between Korean and Chinese, it is difficult to fine the corresponding language that is completely consistent with the meaning and form of the original language, which increases the difficulty of translation. Since now, there are few studies who have explored the problem of nominalization from the perspective of translatology. However, it is necessary to make such study. Under this context, this paper selects two novels and one collection of poetry as the corpus data, investigating the phenomenon of nominalization in terms of Korean through the practical translation cases and summarizing in terms of the translation methods. There are several ways of actualizing the nominalization in Korean. Among this part, ‘-m/um’ is able to be regarded as both noun ending and noun-derivational suffix to actualize the nominalization. They share the same morphology. First of all, this paper summarizes the characteristics of the noun ending ‘-m/um’ and the noun-derivational suffix ‘-m/um’ to help distinguish them through investigating the previous research. Then, noun-derivational suffix is regarded as the core to make the research and the case analysis. Finally, through the analysis of corpus, this paper summarizes six types of translation methods, which are the corresponding words, nominalization, addition, omission, transformation and substitution.
