Morphology

clandestine + operation

The meaning 'a secret planned activity' is directly and compositionally derived from 'clandestine' (hidden/secret) + 'operation' (a planned activity), following a regular adjective + noun pattern. This is a transparent, non-idiomatic combination that is cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE meaning.

Etymology

Clandestine operation may come from an old Latin word 'clam' meaning 'secretly'. Think of clandestine as 'secret' and operation as 'planned action', so the phrase means a planned action that is kept hidden.
