Help a girl to get rid of men (3)
I believe the answer is:
aid
'help' is the definition.
(synonyms)
'a girl to get rid of men' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
The remaining letters 'id' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aid that I've seen before include "charity" , "Help or support" , "Help or succour" , "Help. Assist" , "Auxiliary" .)
