The syntax of nominal modification and complex noun phrases in Siwkolan Amis

This work investigates the syntax of nominal modification involving the linker a in Siwkolan Amis, one of the dialects of Amis, an Austronesian language spoken in Taiwan. Based on the two observed types of NP-ellipsis patterns and the formal licensing condition, I argue that Amis displays two types of modification. Modifiers in direct modification are functional heads projecting extended functional projections of NP, whereas those in indirect modification are modifier phrases base-generated at [Spec, ModP]. This distinction adds weight to J. Wu's (2003) view that relative clauses and description-denoting modifiers marked by -ay are clausal modifiers that have a full-fledged CP structure from a cartographic perspective. Furthermore, I argue that a projects the Modifier Phrase (ModP) and is a modificatory clitic endowed with a [+mod] feature that attaches to a head element moving from a lower head position to form a morphological word. Very much in line with Philip (2012), the proposed analysis suggests that a is endowed with an interpretative profile in marking a modification relation between an extended functional projection (a modifier phrase) and a dependent word (a modified noun) in the nominal domain. Issues involved in dealing with the structure of Amis complex noun phrases are discussed.
