Abstract
The purpose of this paper is to provide a framework for analyzing coordination markers of noun phrases (NP) that include to, ya, mo, and so on. This framework distinguishes three levels of the properties of NP coordination markers which previous studies did not: namely, syntactic level, semantic level, and pragmatic level. At the syntactic level, to and mo are indicated as [+comprehensive]. This implies that these markers always combine the both the elements in coordinated structure with the other elements in the sentence. Ya does not have this characteristic, hence it is indicated as [-comprehensive]. At the semantic level, differences are observed in the motivation to form a "set". To is used to coordinate elements in any set. Ya is used when the hearer can find the same property in the elements. Mo is used when the hearer can predict the appearance of the element in the discourse. At the pragmatic level, to generates the exclusive implicature that implies that there are no additional elements that can be predicated. Ya and mo do not generate exclusive implicature, therefore other elements may exist.
