Which classifier describes layers or thickness, as in pipes or snow?

• A. Depth and Width Morphemes
• B. On-Surface Morphemes
• C. Instrumental Morphemes
• D. Perimeter-Shape Morphemes

Answer: (A)

The idea being tested is how classifiers encode thickness and layering in ASL. Depth and width morphemes are used to show how thick something is or how many layers it has, which fits describing objects like pipes or snow where the important detail is the amount of material from front to back or across. These classifiers capture that dimension directly, conveying the object’s volume and layered structure. In contrast, on-surface morphemes describe whether something is on a surface, instrumental morphemes indicate tool use, and perimeter-shape morphemes describe the outer boundary or outline—properties that aren’t about thickness or layered depth. So describing layers or thickness aligns best with depth and width morphemes.
