The purpose of this study is to analyze usages and functions of quotation sentences and quotation verbs in newspaper texts. The newspaper quotes have the functions of factuality, neutrality, expressiveness, expert contribution, and personal involvement. If we analyze usages of quotation verbs, we can explain the functions of quotation sentences in newspaper texts. The corpus for the study consisted of newspaper texts from '21st Century Sejong Project' corpus. It comprises around 250,000 words in newspaper reports and around 250,000 words in newspaper editorial articles. I analyzed the quotation sentences and measured the ratio of frequency of quotation verbs. The results show that the citations of statement are more than the citations of thought in newspaper reports. But the citations of thought are comparatively frequent in newspaper editorial articles. From this we may know that journalists cite other's statements mostly in newspaper reports. But editors cite their thoughts and assertions in newspaper articles more than in newspaper reports. Using the quotation sentences in reports, the journalists express that cited statements are objective and authentic. And using the quotation sentences in editorial articles, the editors show foundation for their assertion. And '-다고 하-' in articles has function of periphrasis for declining to assert.
