Possessive pronouns as oblique DPs: Linkers and affix stacking

In many familiar European languages, e.g. German or Italian, possessive pronouns agree in φ-features with their head noun. We argue that they are genitive pronouns, endowed with an extra φ-features set. As such, they are part of a range of phenomena including case stacking and linkers uni-fied under the historical-typological label of Suffixaufnahme. We express the formal basis for this unification as the Stacking Generalization (sec-tion 1). We then apply our analysis to the narrower domain of facts in-volving possessive pronouns, specifically in Balkan and Romance lan-guages. We further find that 1/2P pronouns present a richer stacking structure than their 3P counterparts (section 2). We examine this latter fact in the context of a more general phenomenon, whereby the 1/2P vs 3P Person split not only tends to correlate with different case and agreement alignments – but seems to govern the morphological expression of case and agreement itself, in terms of richer vs poorer content (section 3).
