Towards a typology of morphological case

Adposition phrases in morphologically impoverished languages have a function similar to nouns with morphological cases in morphologically rich languages, leading some researchers to argue that at least some cases belong to the category P. The aim of this paper is to investigate whether all cases can be analysed as Ps. The focus is on partitive case in Finnish. Whilst the ‘local’ cases in many languages appear to be strong candidates for analysis as members of the category P, it will be argued that partitive case (and genitive in languages where there is no distinct partitive) spells out a functional head between P and D, and that it properly belongs to the D-system (quantifiers or determiners), not the P-system. Thus morphological cases do not form a coherent category in syntax. Instead, morphological case paradigms relate to one of three different syntactic items: (i) uninterpretable features (structural cases), (ii) PP structures (cases expressing spatial or thematic relations), and (iii) determiner or quantifier projections (partitive, and partitive uses of genitive). Possible extensions of the analysis to other languages (German, Tongan and English) are explored.
