The aim of this article is to deal with the three properties of ‘-eodo doida’. (i) An utterance including ‘-eodo doida’ which means to permit constitutes adjacency pairs with an utterance of the request for permission. (ii) The speaker who has a higher deontic status than a hearer within conversation can utter with ‘-eodo doida’. In general the speaker who has a higher institutional status also has both a higher deontic status and a higher epistemic status than the hearer. However, an epistemic status could be adjusted during conversation, which affects who has a higher deontic status. (iii) The speaker who recognizes the hearer’s state allows the hearer to act what (s)he wants to do with using ‘-eodo doida’. The speaker can strengthen a social bond with the hearer by using ‘-eodo doida’. However, the speaker may experience a kind of loss by using assertive ‘-eodo doida’. The speaker can migrate the responsibility of the speaker while using the expressions next to ‘-eodo doida’.
