A second mowing at the farm perhaps (9)
I believe the answer is:
aftermath
'a second mowing' is the definition.
I can't tell whether this definition defines the answer.
'at the farm perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'at'+'the'+'farm'='atthefarm'
'atthefarm' is an anagram of 'AFTERMATH'.
Can you help me to learn more?
(Other definitions for aftermath that I've seen before include "Sequel" , "Consequence of an event, situation that follows" , "Situation following as consequence or result" , "Wake" , "Outcome of being at the farm" .)
