Morphology

solid + rock

The meaning 'strong and reliable foundation or support' is directly and predictably built from 'solid' (stable, dependable) + 'rock' (a stable or supporting thing/person), so a B1 learner who knows both words can infer the metaphorical sense. This adjective+noun composition and the rock-as-stability metaphor are cross-linguistically common, making the expression readily comprehensible.

Etymology

Solid rock comes from the simple image of a hard stone: solid and rock that do not move even in strong storms. So calling someone a solid rock means they are a steady 'foundation' or 'support' you can trust.
