It's wrong to be stood on its head (4)
I believe the answer is:
evil
'it's wrong' is the definition.
(associated in meaning)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for evil that I've seen before include "Immorality" , "Wicked, sinful" , "no good in this puzzle" , "Live badly in depravity" , "Live (anag.)" .)
