Woman has wise man to face (6)
I believe the answer is:
visage
'to face' is the definition.
(visage is a kind of face)
'woman has wise man' is the wordplay.
'woman' becomes 'Vi' (short for Violet).
'has' means one lot of letters go next to another.
'wise man' becomes 'sage' (sage is a kind of wise man).
'vi'+'sage'='VISAGE'
(Other definitions for visage that I've seen before include "A person's face, countenance" , "Face, aspect" , "Mug" , "Clock" .)
