County in need of pole for flag (4)
I believe the answer is:
wilt
'for flag' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for wilt that I've seen before include "fade" , "lose energy?" , "tire?" , "Shrivel and collapse" , "Droop in the heat" .)
