The woman's about right, women nag (5)
I believe the answer is:
shrew
'nag' is the definition.
(thesaurus)
'the woman's about right women' is the wordplay.
'the woman' becomes 'she' (I've seen this before**).
'about' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'women' becomes 'w'.
'she' enclosing 'r' is 'shre'.
'shre'+'w'='SHREW'
(Other definitions for shrew that I've seen before include "Vixen" , "Mouse-like creature" , "Small mouselike animal" , "Nagging woman" , "Petruchio tamed one" .)
