Need month set apart for recovering (2,3,4)
I believe the answer is:
on the mend
'for recovering' is the definition.
(on the mend means recovering or recuperating)
'need month set' is the wordplay.
'set' is an anagram indicator (instruction to set the letters).
'need'+'month'='needmonth'
'needmonth' with letters rearranged gives 'ON THE MEND'.
'apart' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for on the mend that I've seen before include "undergoing recovery?" , "Recovering from an injury or illness" , "convalescing" , "Looking up" , "Becoming better in health" .)
