This research is aimed to seek an alternative and criticize the argument of useless that 2000s appeared in earnest. The policy of standard language with Seoul as the center destroys using dialect and language variety. The standard language was criticized considerably because it was likely different from definition that “The language of moderm people are using the word widely”. An alternative to this, these are the way that make the best use of “the plural standard language” or we don`t need to use the regulation of standard language autonomously. These arguments are not irrelevant to appear a left leaning ideology that influenced by the 2000s social atmosphere or politics. Generally, the useless of standard language regulation emphasizes the role of “dictionary”. But these arguments are difficoult to realize considering the linguistic feature of Korea. Therefore the reaserch proposed to discriminate between the role and the illustration to the flexibility of standard language.
