Morphology

police + detective

The noun phrase is fully compositional: 'police' (law-enforcement organization) modifies 'detective' (an investigator), so the meaning is simply a detective who works for the police. This head‑modifier compound follows a common cross‑linguistic pattern, so a B1 learner who knows both constituents will readily infer the combined meaning.

Etymology

Police detective shows a police officer whose job as a detective is to find and uncover hidden facts by following clues, talking to witnesses, and collecting evidence. That's why it means 'to investigate crimes and gather evidence'.
