Noble, not having a chance (7)
I believe the answer is:
imperil
'chance' is the definition.
(thesaurus)
'noble not having a' is the wordplay.
I cannot quite see how this works, but
'a' could be 'per' and 'per' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for imperil that I've seen before include "Expose" , "put at hazard" , "Put at risk" , "Put in danger" , "Endanger" .)
