Starting from the traditional distinction between R(elational) and Q(u
alifying) adjectives, we divide the former into two major subclasses:
Th(ematic) and C(lassificatory) adjectives. This distinction has effec
ts on semantic interpretation and word order. Th-adjectives obey the t
hematic hierarchy and C-adjectives follow patterns of subclassificatio
n of objects in different domains. R-adjectives are maximal projection
s mapped into specifier positions. Spanish, contrary to English, has o
vert raising for gender and number checking on the noun and the adject
ives. R-adjectives are argued to form syntactic clusters by a series o
f adjunctions that satisfy antisymmetric c-command requirements and mi
nimality constraints on movement.
