In this paper, we attempt to research to identify the meaning of the ладн о as a discourse marker. This study analyzes and summarizes the meanings of ладно revealed in previous studies through the analysis of the research in terms of lexical terms, Kuznetsov(1998) and Wachtel(2013). However, each of the study method turned out to be a limit is to derive a systematic means of ладно as discourse marker. The analysis of Kuznetsov (1998) was only a dictionary description of meanings, and limited to deriving technical meanings expressed by parts of speech. On the other hand, Wachtel (2013) considered ладно as a vocabulary, and attempted to analyze the meaning of ладно at the level of discourse, but ultimately, there was no explanation on what criteria the meaning as a discourse marker was derived from. In this paper, we focus on the meaning of ладно as a discourse marker more systematically. Firstly, ладно as an adverb function represents the main meaning of the judgment or position of the speaker who uttered ладно. Secondly, as a particle, the purpose of firing ладно is that the purpose of seeking the other's intention is dealt with more heavily. Next, we look at the meanings derived from the combination of ладно and other vocabulary words 'ну and да'. 'ну ладно' represents the contextual meaning of ending the dispute, ending the discourse, and in the case of да ладно, it can be interpreted as a pragmatic signal that a certain limit has been reached. On the other hand, ну да ладно, like да ладно, expresses the meaning of ending the current utterance or situation.
