Number of points about a woman (5)
I believe the answer is:
seven
'number' is the definition.
(seven is a kind of whole number)
'points about a woman' is the wordplay.
'points' becomes 'sn'.
'about' means one lot of letters goes inside another.
'a woman' becomes 'eve' (Eve is an example**).
'sn' placed around 'eve' is 'SEVEN'.
'of' acts as a link.
(Other definitions for seven that I've seen before include "Numeral" , "Number of colours of the rainbow" , "Film" , "Number of sisters in Sussex" , "So many ages of man (AYLI)" .)
