The purpose of this thesis is to examine dictionary headwords of sentence connectives that are constituted of Auxiliary Particle ‘-neun(는)’ to set the standard of dictionary headwords. The 『Hangul』, 『Kimmin』, 『Yunsei』, 『Kuglip』, and 『Sahoi』 dictionaries' lack standards on dictionary headwords, especially on sentence connectives constituted of Auxiliary Particle ‘-neun(는)’. So the aspect on headwords of sentence connectives differ from one dictionary to another. Moreover, it differs within the same dictionary. One of the most important standards is the change of syntactic-semantic function, dropping or alternation of pre-final endings, and amalgamation of shape and semantic function. According to the standards, ‘-daganeun(다가는2) ; -kon2(곤2), -kon3(곤3) ; -kironeun(기로는) are grammaticalized endings, so these endings should be recorded in the dictionary. The other endings are not grammaticalized, so these endings are not recorded in the dictionary.
