Angled or curved (4)
I believe the answer is:
bent
This clue is a double definition.
'angled' is the first definition.
(I've seen this in another clue)
'curved' is the second definition.
(I've seen this before)
(Other definitions for bent that I've seen before include "Out of shape, curved" , "Dishonest, corrupt" , "Dishonest - inclination" , "Crooked - tendency" , "Corrupt; grass stalk" .)
