"Classifiers" American Sign Language (ASL)
A classifier (in ASL) is a sign that represents a general category of things, shapes, or sizes. A predicate is the part of a sentence that modifies (says something about or describes) the topic of the sentence or some other noun or noun phrase in the sentence. (Valli & Lucas, 2000) Example: JOHN HANDSOME.
