The current study synthetically analyzes the contracted negative form “X + 잖.” This study shows that contracted negative words with the form of X + 잖 can be completed either with or without a pre-contraction word(X). In case in which X exists, a negative particle is combined with X to make a contracted negative vocabulary. In the absence of X, on the other hand, a completely new contracted negative word is created. The aspects of contraction is affected by various factors, such as the style changes of X, the existence of pre-contraction and post-contraction vocabulary, and semantic relations between words. In this study, 19 words were selected from all the words with the form of X + 잖 that have been registered in the dictionary and were further classified by their types. The following chart briefly demonstrates the result of study.
