Morphology
The compound 'box wrench' transparently signals a type of wrench related to 'box'—a B1 learner who knows both words will infer it is a wrench that has some boxed or enclosed feature. However, the precise technical sense (a closed/socket end that fits over a nut or bolt) is specialized and not fully predictable from the constituents alone, so partial prior exposure would help.
Etymology
Box wrench: The tool name box wrench comes from the closed end that fits over a nut like a small box. That full grip helps the wrench hold the nut so you can 'tighten' or 'loosen' it without slipping, and that is why the name stuck.
