Renewed fame isn't obvious (8)
I believe the answer is:
manifest
'obvious' is the definition.
('manifest' can be similar in meaning to 'obvious')
'renewed fame isn't' is the wordplay.
'renewed' indicates an anagram.
'fame'+'isnt'='fameisnt'
'fameisnt' anagrammed gives 'MANIFEST'.
(Other definitions for manifest that I've seen before include "List of ship's cargo or passengers" , "Plain - cargo list" , "Document listing a ship's contents for customs purposes" , "Clear, obvious" , "Express" .)
