Woman has space to finish (5)
I believe the answer is:
sheen
'finish' is the definition.
(thesaurus)
'woman has space' is the wordplay.
'woman' becomes 'she' (**).
'has' means one lot of letters go next to another.
'space' becomes 'en'.
'she'+'en'='SHEEN'
'to' is the link.
(Other definitions for sheen that I've seen before include "Surface gloss" , "Oil slick" , "splendid clothing" , "Sureface shine" , "Radiance" .)
