Morphology

ironclad + agreement

The noun phrase is compositionally predictable: an adjective meaning 'unable to be broken or altered' (ironclad) directly modifies 'agreement', so a learner who knows both constituents can infer a firm, unbreakable contract. This adjectival + noun pattern is a straightforward semantic composition and is cross-linguistically common, making it transparent to B1 learners who know the parts.

Etymology

Ironclad agreement comes from old warships called ironclads, which were covered in iron plates and were very hard to damage. So an ironclad agreement means an agreement that is 'very firm' and 'hard to change' or break.
