Morphology

rock + salt

The meaning 'coarse crystalline sodium chloride' is directly and predictably derived from combining 'rock' (mineral/solid mass) with 'salt' (sodium chloride): i.e., salt in rock/crystalline form. This straightforward noun+noun compounding pattern is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE's sense and typical uses (e.g., de-icing).

Etymology

Rock salt comes from the idea of salt that is like a rock, with big hard crystals found in the ground. That's why rock salt today means coarse salt used for 'de-icing' roads or in cooking.
