Woman given new uniform (4)
I believe the answer is:
even
'uniform' is the definition.
(both can mean equal or level)
'woman given new' is the wordplay.
'woman' becomes 'eve' (Eve is an example).
'given' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'eve'+'n'='EVEN'
(Other definitions for even that I've seen before include "Going so far as to" , "on level terms" , "Tied" , "Flat, regular" , "Not bumpy" .)
