Hidden - but not from a gunman? (7)
I believe the answer is:
covered
'hidden' is the definition.
(covering is a kind of hiding)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for covered that I've seen before include "given protection" , "Insured; enveloped" , "Travelled (a distance); protected" , "Overlaid with something" , "Reported" .)
