Reputation's up! (8)
I believe the answer is:
standing
I believe this is a double definition.
'reputation's' is the first definition.
(thesaurus)
'up' is the second definition.
(I've seen this before)
(Other definitions for standing that I've seen before include "Being a candidate - status" , "Prestige" , "Bearing" , "Still in" , "Status - on one's feet" .)
