Back on the list of the famous (7)
I believe the answer is:
notable
'the famous' is the definition.
(thesaurus)
'back on the list' is the wordplay.
'back' says the letters should be written in reverse.
'the list' becomes 'table' (I've seen this before).
'on' back-to-front is 'no'.
'no'+'table'='NOTABLE'
'of' is the link.
(Other definitions for notable that I've seen before include "Remarkable, worthy of comment" , "Unusual" , "Big noise" , "Celebrated" , "VIP" .)
