Go back and make another concession? (6)
I believe the answer is:
recede
'go back' is the definition.
(I've seen this before)
'another concession?' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'concession?' becomes 'cede' (I am not sure about this - if you are sure you should believe this answer much more).
're'+'cede'='RECEDE'
'and make' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for recede that I've seen before include "Move backward" , "Decline" , "Start balding" , "Go backwards" , "Go back, ebb" .)
