And not male standard (4)
I believe the answer is:
norm
'standard' is the definition.
(I know that norm is a type of standard)
'and not male' is the wordplay.
'and not' becomes 'nor' ('nor' means 'and also not').
'male' becomes 'm' (common abbreviation).
'nor'+'m'='NORM'
(Other definitions for norm that I've seen before include "Average result" , "Standard, criterion" , "Average level of performance" , "Mean" , "Drawing stick" .)
