Topicality and (non-)specificity in Mandarin

Current analyses of specificity are unable to provide an explanatory account for why specific and nonspecific uses of indefinites are available. While Abusch (1994), Reinhart (1997), and Kratzer (1998) provide successful mechanisms for deriving specific readings, they do not provide a fundamental explanation for the availability of this mechanism. This is due to the fact that specific indefinites are treated as involving an interpretive component or procedure unique to themselves: storage (Abusch) or choice function (Reinhart and Kratzer), for example. It would be preferable if specific indefinites could be understood as deriving from the use of independently motivated meaning components and interpretive mechanisms. Here I will pursue the idea, building on Portner & Yabushita (1998), that specificity has to do with the indefinite's interaction with a topical domain (note similarities with the proposals of Enç 1991, Cresti 1995, and Schwarzschild 2000). In this conception, specificity is a matter of degree: the narrower the topical domain, the more specific the indefinite. More precisely, sentences containing specific indefinites will be understood as involving ordinary existential quantification in combination with a topical domain function.
