Morphology

hook + spanner

The noun–noun compound 'hook spanner' is directly compositional: combining 'hook' (a curved implement) with 'spanner' (a wrench) yields a type of wrench that has a hook. This follows standard English compounding patterns and a B1 learner who knows both constituents can reasonably infer it is a spanner with a hooked end used to engage slots or notches.

Etymology

The noun hook spanner comes from the tool's shape: a hook on a spanner fits into a slot on a round nut so it can catch and turn the nut. That's why it means 'a wrench used to turn circular nuts with a slot'.
