The paper presents some evidence for the superiority of the analysis in terms of N-movement over the Head-subject parameter to account for superficial differences in Romance and Germanic noun phrases. The restrictions on adjective ordering and cooccurrence supports the idea that APs are SPECs rather than adjuncts, and are divided into different classes on the basis of their interpretation; each class must be assigned a fixed position in the structure. The relative order of adjectives is the same crosslinguistically, and the only difference between Romance and Germanic is the position of the head N with respect to the sequence of adjectives. The residual cases of mirror image effects are explained as incorporations.
