Plain destitution unveiled (5)
I believe the answer is:
overt
'plain' is the definition.
(I've seen this in other clues)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for overt that I've seen before include "This is not hard to see" , "Trove (anag.)" , "not disguised" , "Clear" , "Open, up front" .)
