Prosecutes woman and school (4)
I believe the answer is:
sues
'prosecutes' is the definition.
(I've seen this before)
'woman and school' is the wordplay.
'woman' becomes 'sue' (woman's name).
'and' is a charade indicator (letters next to each other).
'school' becomes 'S'.
'sue'+'s'='SUES'
(Other definitions for sues that I've seen before include "Proceeds legally against" , "Takes legal action against" , "Takes to court" , "Takes a case against" , "Prosecutes" .)
