Facial make-up used by the police? (9)
I believe the answer is:
identikit
This clue might be a double definition.
'facial make-up' is the first definition.
The definition suggests a singular noun which matches the answer.
'the police?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'used by' acts as a link.
Can you help me to learn more?
(Other definitions for identikit that I've seen before include "image maker" , "Police hunt picture" , "Reconstructed image of a criminal" , "uninteresting" , "Police ID picture" .)
