This study aims at investigating distinct features of derivational suffixes that compose Human Noun in the Post-Modern Period. At that time, there are lots of derivational words, and some Human Noun were derived by attaching derivational suffixes like '-nim, -i, -kun, -jani/jaengi, -tongi'.Whenever we observe the history of language, we easily find that there are lots of changes of language, for example, vocabularies, grammars, and so on. Lots of vocabularies are formed newly and some didn't be used anymore. Those phenomenon are easily found in suffixes, too. So this study would like to examine that language change was found in derivational suffixes in Post-Modern Period.First of all, we think about suffixes like '-nim', '-i', '-kun', '-jangi/jaengi', and '-tongi/-tungi'. These suffixes derived Human Noun. Those suffixes had something in common, but had nothing in common, specially in distribution, and meaning like [+honorific], [-honorific], [+Human].This study shows that these suffixes get wider in functional load. For example '-nim', '-i', '-kkun' are attached to lots of roots, and compose lots of Human Noun than Post-Modern Period. However these days the distributional restriction of '-jani/-jaengi', '-tongi' are narrower than that time, and also the meaning of '-jani/-jaengi', '-tongi' are changed than before.
