A note on labeling, Berber states 
and VSO order

Berber nouns appear in two syntactically-conditioned morphological forms. Subjects in VSO configurations, objects of (most) prepositions and clitic-doubled direct objects manifest the construct state , CS. Elsewhere, nouns appear in the free state , FS. I argue that CS is the form of a noun that merges with a head K, situated above vP and below T. Following Chomsky (2013), the subject phrase must raise out of vP in order for vP to get labeled. K is its target. From Kayne (2002, 2004), I borrow the idea that P is configured above vP and attracts a noun to a twinned head K. Clitic-doubled objects, unlike non-doubled ones, are also on the edge of vP and labeling requirements force them to raise higher, again to K.
