Delay being freed indefinitely (5)
I believe the answer is:
defer
'delay' is the definition.
(I know that defer is a more specific form of the action delay)
'freed indefinitely' is the wordplay.
'indefinitely' indicates an anagram (indefinitely can mean vaguely or uncertainly).
'freed' anagrammed gives 'DEFER'.
'being' is the link.
(Other definitions for defer that I've seen before include "Give precedence to" , "Allow precedence (to)" , "Postpone - submit" , "stall" , "Delay" .)
