Unfit to be an eminent person? (7)
I believe the answer is:
notable
'person?' is the definition.
(notable is a kind of person)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for notable that I've seen before include "Famous or memorable" , "Significant or distinguished" , "Worth remembering" , "Widely known and esteemed" , "VIP" .)
