Poorly run in smog, very deficient in recovery (9)
I believe the answer is:
misgovern
'smog very deficient in recovery' is the definition.
I can't judge whether this definition defines the answer.
'poorly run' is the wordplay.
'poorly' becomes 'mis' (I can't justify this - if you can you should give a lot more credence to this answer).
'run' becomes 'govern' (both can mean to rule over).
'mis'+'govern'='MISGOVERN'
'in' is the link.
Can you help me to learn more?
(Other definitions for misgovern that I've seen before include "Rule badly" , "rule unfairly" , "run badly" .)
