Woman to dine out (4)
I believe the answer is:
enid
'woman' is the definition.
'dine out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'dine' is an anagram of 'ENID'.
'to' acts as a link.
(Other definitions for enid that I've seen before include "Geraint's loved one" , "Writer of children's books, d. 1968" , "& 18 Down Children's author" , "Miss Blyton" , "Arthurian wife" .)
