Chicken fattened by the French woman (5)
I believe the answer is:
helen
'woman' is the definition.
'chicken fattened by the french' is the wordplay.
I cannot really see how this works, but
'the french' could be 'le' ('the' in French) and 'le' is located in the answer.
'chicken' could be 'hen' (hen is a kind of chicken) and 'hen' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for helen that I've seen before include "Woman abducted to Troy" , ""The face the launched 1,000 ships"" , "Immortal beauty of Troy" , "The Greek army sailed to Troy to get her back" , "Famous beauty of Troy" .)
