Did they attend to women unfairly accused once? (5-7)

'unfairly accused once?' is the definition.
I can't tell whether this definition defines the answer.

'did they attend to women' is the wordplay.
I cannot really understand how this works, but
'to' is found in the answer.
'women' could be 'w' (standard abbreviation) and 'w' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
