Fall of rain out in wild (9)
I believe the answer is:
ruination
'fall' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'rain out in wild' is the wordplay.
'wild' indicates an anagram.
'rain'+'out'+'in'='rainoutin'
'rainoutin' anagrammed gives 'RUINATION'.
'of' is the link.
Can you help me to learn more?
(Other definitions for ruination that I've seen before include "Complete destruction or collapse" , "total disaster" , "Complete downfall" , "State of destruction" , "Devastation" .)
