It is also aimed to analyze how the discourse function of the construction of the auxiliary verb 'hada' that express the meaning of 'conditions/assumptions' is performed, and from that, to investigate what the mechanism that the construction of the auxiliary verb 'hada' performs various semantic functions at the discourse level is. As a result of the study, it was shown that the construction of the auxiliary verb 'hada' performs the primary grammatical meaning by adding meaning of linguistic features such as connective ending which is combining with the preceding verb, final ending, particles, formulaic expression. And that meaning performs various discourse functions according to the contextual conditions such as the formality, the relationship between participant's of utterance, contents of utterance, speaker's attitude. From this, it can be seen that the function of discourse is not fixed, it is a new additional meaning obtain from the discourse level including various contexts, and it is characterized by contextual dependency that can change if some of these conditions are different.
