In this paper, I examine where nanka in ordinary conversations comes from. Here I take into consideration the relationship between nanka and "concept" (Halliday 1994:59) in "information unit" (ibid.). From analysis and discussion, I point out (1) nanka is not "a habit of saying" to make introductory remarks, but discourse marker which follows new concepts for hearers and (2) nanka is born of metaphorical grammaticalization from pronoun and metonymic one from adverbial particle to discourse marker. Moreover, I make clear the process of grammaticalization concerning nanka. That is, nanka is derived from pronoun expressing what is unspecified. Later, influenced by adverbial particle, it marks the whole utterances after nanka as something vague and is used in order to connect to clear contexts before nanka. Then, it is grammaticalized as an expression that implies the speaker's attitude to or judgement on what remains vague after nanka.
