Happened to turn up a month before woman has done likewise (8)
I believe the answer is:
befallen
'happened to' is the definition.
('befall' can be a synonym of 'happen to')
'turn up a month before woman has done likewise' is the wordplay.
I cannot quite understand how this works, but
'turn' could be 'fall' (falling is a kind of turning) and 'fall' is located in the answer.
'before' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
The remaining letters 'ben' 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).
(Other definitions for befallen that I've seen before include "Came to pass" , "(Having) happened to (someone)" .)
