Woman to have a meal sent back (4)
I believe the answer is:
enid
'woman' is the definition.
'have a meal sent back' is the wordplay.
'have a meal' becomes 'dine' (I've seen this before).
'sent back' shows that the letters should be reversed in order.
'dine' in reverse letter order is 'ENID'.
'to' acts as a link.
(Other definitions for enid that I've seen before include "Dine out on this girl's name also" , "Lady" , "Geraint's loved one" , "W - - Blyton" , "'... Blyton, children's author (4)'" .)
