She may have been banned for changing her name (5)
I believe the answer is:
bride
'she' is the definition.
'have been banned for changing her name' is the wordplay.
I cannot really understand how this works, but
'her' could be 'de' and 'de' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'may' is the link.
Can you help me to learn more?
(Other definitions for bride that I've seen before include "woman in front of train" , "Newlywed" , "Groom's partner" , "presumably honeymoon for me?" , "Wife of groom" .)
