Fellows figure to get better (4)
I believe the answer is:
mend
'get better' is the definition.
(synonyms)
'fellows figure' is the wordplay.
'fellows' becomes 'men' (fellow can mean a man).
'figure' becomes 'd' (I can't explain this - if you can you should give a lot more credence to this answer).
'men'+'d'='MEND'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for mend that I've seen before include "Put right" , "'Restore, fix (4)'" , "Return to health; repair" , "Fix, repair" , "Heal" .)
