Nice to be rid of incompetent leader after ten years resulting in social decay (9)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
decadence
'decay' is the definition.
(I know that decay can be written as decadence)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for decadence that I've seen before include "Perishing state" , "Moral or cultural decline" , "Degeneration" , "Corruption" , "Decline in quality" .)
