Put off being freed, perhaps (5)
'put off' is the definition.
('defer' can be a synonym of 'put off')
'freed perhaps' is the wordplay.
'perhaps' indicates an anagram.
'freed' with letters rearranged gives 'DEFER'.
'being' acts as a link.
(Other definitions for defer that I've seen before include "stall", "Yield to another's opinion", "Play for time", "Yield to authority", "Give precedence to".)
