Morphology

hook + wrench

The noun combines 'hook' (a curved implement) with 'wrench' (a tool for turning), so the overall meaning — a wrench with a hook-shaped end — is directly inferable from the constituents. This is a regular, compositional English compound noun pattern (and mirrors similar compounds in other languages), so a B1 learner who knows the parts would readily understand it.

Etymology

Hook wrench comes from the tool's shape: a wrench with a hook at the end that grabs the edge of a round nut. So, a hook wrench is used 'to turn' round nuts or bolts that have no flat sides.
