Other forms: detectives
A detective is the one who works out who did it. Not the officer standing at the tape, but the one in the room afterwards with the photographs, the phone records and a whiteboard covered in names. A detective knocks on doors, asks the same question three different ways, and waits for the answer to change.
The word covers two jobs at once. A police detective is a rank: you are promoted to detective out of uniform. A private detective is hired by ordinary people, to follow a husband, trace a missing sister, or check what a company has been doing with its money. Detective also sits in front of other nouns: detective work, a detective story, the detective novels people take on holiday. And detective work is what anyone does who pieces something together from small signs, even if all they are solving is who ate the last of the cake.

detective is an investigator.
The Latin verb dētegō meant to detect, and its past participial stem dētēct- is what English detect is built on. Add -ive and you get an adjective, which is how the word began: a detective policeman, a detective officer. English then dropped the noun and left the adjective standing on its own. Later it travelled back out for the books, giving Dutch detective and Russian детекти́в, both meaning a detective novel.
