Decline to set us free again (6)
I believe the answer is:
refuse
'decline' is the definition.
(I know that decline can be written as refuse)
'set us free again' is the wordplay.
'us free' can be anagrammed to 'REFUSE'.
However, I'm unsure how the anagram is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for refuse that I've seen before include "Turn down; waste" , "household rubbish" , "Reject the waste material" , "Turn down - rubbish" , "Decline waste material" .)
