There are two kinds of genitive constructions: genitive pronouns, and genitive NP's (which have an explicit genitive marker, 's, associated with them). It is clear from examples such as her dog returned home and her five dogs returned home vs dog returned home that genitive pronouns function as determiners and as such, they sequence with the rest of the determiners. The features for the genitives are the same as for other determiners. Genitives are not required to agree with either the determiners or the nouns in the NPs that they modify. The value of the agr feature for an NP with a genitive determiner depends on the NP to which the genitive determiner adjoins. While it might seem to make sense to take their as 3pl, my as 1sg, and Alfonso's as 3sg, this number and person information only effects the genitive NP itself and bears no relationship to the number and person of the NPs with these items as determiners. Consequently, we have represented agr as unspecified for genitives in Table 19.1. Genitive NP's are particularly interesting because they are potentially recursive structures. Complex NP's can easily be embedded within a determiner.
