Important to be untalented (7)
I believe the answer is:
notable
'important' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for notable that I've seen before include "Impressive" , "VIP" , "Remarkable, worthy of comment" , "Significant or distinguished" , "Unusual" .)
