This paper aims at describing the Opinion-Free Frozen expressions (OFFs) composed of two contrastive sentiment keywords. Although sentiment words occur in OFFs, they do not determine the polarity of the given sentences, which is a problematic issue for the current opinion classification systems that basically work on the detection of sentiment keywords in the sentence. As a matter of fact, OFFs consist of two predicative sequences ending with the repeated inflectional suffixes. In this study, 93 inflectional suffixes are obtained from the list of 360 elements in the Korean electronic lexicon DECO and classified into 4 sub-categories.
