Woman has new uniform (4)
I believe the answer is:
even
'uniform' is the definition.
(thesaurus)
'woman has new' is the wordplay.
'woman' becomes 'eve' (Eve is an example**).
'has' says to put letters next to each other.
'new' becomes 'n'.
'eve'+'n'='EVEN'
(Other definitions for even that I've seen before include "end of the day, reading poetry" , "neck and neck" , "50-50" , "Yet; level" , "Quits - flat" .)
