The goal of this paper is two-fold: First, I present and analyze a restricted set of dimensional nominal property concepts (DNPC) in Levantine Arabic (LA) (e.g., Tuul "tallness", ?arD "width") whose semantics supports the syntactic analysis of property concepts under the uniformitarian view (Menon and Pancheva, 2014) and presents a direct theoretical challenge to the semantic analysis under the transparent view (Francez and Koontz-Garboden, 2015). Second, I propose an explanation to the facts based on uniformitarian assumptions along with other independently motivated standard assumptions.
