Artiste with the stomach for it (5,6)
I believe the answer is:
belly dancer
'artiste' is the definition.
(thesaurus)
'with the stomach for it' is the wordplay.
'with' is a charade indicator (letters next to each other).
'the stomach' becomes 'belly' (synonyms).
'for it' becomes 'dancer' (I can't explain this - if you can you should believe this answer much more).
'belly'+'dancer' is 'BELLY-DANCER'.
Can you help me to learn more?
(Other definitions for belly dancer that I've seen before include "Exotic Middle Eastern performer" , "Performing gyrator of the tummy" , "manoeuvring needed for such?" , "Female performer" , "Middle Eastern entertainer" .)
