Maintain no central banks free from blame (8)
I believe the answer is:
innocent
'free from blame' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'maintain no central banks' is the wordplay.
'banks' indicates the answer is hidden within the clue (the clue contains or banks the answer).
'INNOCENT' can be found hidden inside 'maintain no central'.
Can you help me to learn more?
(Other definitions for innocent that I've seen before include "Without blame or without guile" , "Without blame or guilt" , "without blood on hands?" , "otherworldly?" , "Without sin" .)
