She accepts backup just the same (5)
I believe the answer is:
madam
'accepts backup just the same' is the definition.
I can't tell whether this defines the answer.
'she' is the wordplay.
I cannot really see how this works, but
'she' could be 'mada' and 'mada' is found in the answer.
A single letter 'm' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for madam that I've seen before include "How one may address a woman" , "Conceited girl (colloq.)" , "Stuck-up girl" , "Make wildly happy" , "Woman with status - girl with bad manners" .)
