She has the stomach for performing (5,6)
I believe the answer is:
belly dancer
'she has' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'stomach for performing' is the wordplay.
'stomach' becomes 'belly' (synonyms).
'for performing' becomes 'dancer' (I can't justify this - if you can you should give a lot more credence to this answer).
'belly'+'dancer'='BELLY-DANCER'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for belly dancer that I've seen before include "manoeuvring needed for such?" , "Performing gyrator of the tummy" , "Exotic Middle Eastern performer" , "Female performer" , "Middle Eastern entertainer" .)
