Calgary Working Papers in Linguistics, 28(Fall), 97-116.2371-2643http://hdl.handle.net/1880/51475This paper presents phonological and syntactic evidence from Irish demonstratives to argue for phrasal structure and an addition to the syntactic hierarchy of projections in the nominal domain – the demonstrative phrase (DemP). Previously in the literature, demonstratives have been analyzed as belonging to the same category as adjectives (Leu 2008), or as belonging to the same category as determiners (Wiltschko 2009). In this paper, I explore the predictions made by these analyses by extending them to Irish. The Irish data refutes both of those analyses because of obligatory co-occurrence with determiners, and a lack of adjective agreement. Phonological evidence (consonantal weakening effects) further allow me to argue that, unlike what is proposed by Cinque (2005) or Roberts (to appear), the demonstrative projection is not low in the nominal structure, but is actually external to the determiner projection and very high in the structure. I conclude this paper by making cross-linguistic predictions which are briefly extended to English demonstratives and outlining avenues for future research in applying these hypotheses to unrelated, non-Indo-European languages.enLinguisticsIrish languageSyntaxGrammar, Comparative and general--Locative constructionsPhonologyGrammar, Comparative and general--Demonstrativesjournal article10.11575/PRISM/28990
