Woman within crossword diagram? (6)
I believe the answer is:
ingrid
'woman' is the definition.
'within crossword diagram?' is the wordplay.
'within' becomes 'in'.
'crossword diagram?' becomes 'grid' (crossword grid).
'in'+'grid'='INGRID'
(Other definitions for ingrid that I've seen before include "Riding (anag) - girl's name" , "___ Bergman, Swedish actress" , "girl" , "A lady" .)
