Go back and try another cure (7)
I believe the answer is:
retreat
'go back' is the definition.
(to retreat is to withdraw or go back)
'another cure' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'cure' becomes 'treat' (I've seen this before).
're'+'treat'='RETREAT'
'and try' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for retreat that I've seen before include "asylum" , "What cowards might do" , "Withdraw from battle" , "The Priory, say" , "Climb down" .)
