Morphology

plain + clothes + detective

The phrase literally combines 'plain' (ordinary) and 'clothes' (wearing) with 'detective', so a learner who knows the constituent words can infer it means a detective wearing ordinary clothes instead of a uniform. This compositional pattern is common cross-linguistically and follows straightforward English noun-modifier rules, making the meaning immediately accessible to a B1 learner.

Etymology

Plain clothes detective comes from police who wore plain clothes instead of a uniform so the detective would not stand out in a crowd. That's why it means 'a police officer who works in regular clothes to avoid attention'.
