Praetorian rank to make amends (10)
I believe the answer is:
reparation
'amends' is the definition.
(synonyms)
'praetorian rank' is the wordplay.
'rank' indicates anagramming the letters (a rank or rotten spelling of the letters).
'praetorian' with letters rearranged gives 'REPARATION'.
'to make' is the link.
(Other definitions for reparation that I've seen before include "damages" , "process of putting things right again" , "compensation" , "make redress" , "The making of amends for a wrong" .)
