Toyuu-reduplication and the Structure of Extended Nominal Projections in Japanese

This study analyzes one type of reduplication in Japanese, which I refer to as toyuu-reduplication, from a syntactic and semantic point of view. In toyuu-reduplication, a noun phrase is reduplicated around the particle toyuu. This paper shows that toyuu-reduplication can be analyzed based on the structure of extended nominal projections proposed by Watanabe (2006, 2010), and Huang and Ochi (2014). More precisely, I propose that toyuu-reduplication has the structure that Japanese postnominal numeral classifiers have. The proposed analysis implies that Japanese manifests two means of lexical support for the Cl head like Chinese: overt realization of the Cl head or noun incorporation.
