Morphology

mare + nostrum

This is a Latin proper name (literally 'our sea') rather than an English compositional phrase, and B1 learners will not reliably know the Latin constituents or derive the sense 'Italian search‑and‑rescue operation' from them. As a fixed proper noun referring to a specific operation and historical concept, its meaning is referential and not predictable from the constituent forms, so it is opaque.

Etymology

Mare nostrum literally means mare 'sea' and nostrum 'our' in Latin. Romans used it to say the Mediterranean was 'their' sea, so today the phrase is used to mean 'the Mediterranean Sea' in historical contexts.
