The purpose of this study is to investigate previous policies and usage of standard loanword in Korea and to find problems and alternatives from a position of supporting the necessity of regulating standard loanword. The current standard language of Korea is following < Korean standard language regulation >(1988) that the nation notified, but < Korean standard language regulation >(1988) is only stipulating pure Korean words(native word) and standard language of Sino-Korean words. However, letters are used for writing words that < loanword orthography > without regulation standard language regulation is unstable by nature. As a result, considerable differences have arisen between the use of loanword and regulation, and many errors are occurring in the language used by the public. This is not only an obstacle in accurate communication, but becomes a factor that the language society distrusts the language standard. Therefore, this study considered that < standard loanword regulation > that conforms to the < standard language regulation > needs to be prepared as a fundamental countermeasure for solving discordance between the linguistic reality and loanword orthography.
