Morphology

lug + wrench

This noun–noun compound is fully compositional: 'lug' identifies the target (the protruding tab or lug nut) and 'wrench' names the tool, so the phrase denotes a wrench for lugs/lug nuts. The modifier+head pattern is common in technical vocabulary and cross-linguistically transparent, so a B1 learner who knows both constituents can readily infer the meaning.

Etymology

Lug wrench gets its name from what it does: the word lug refers to the 'lugs' or nuts that hold a wheel, and a wrench is a tool that turns them. So picture a tool that fits over the wheel 'nuts' to grab and turn them — that's why lug wrench means a tool for loosening or tightening wheel nuts.
