Release slow Orwellian nurse (8)
I believe the answer is:
unfasten
'release' is the definition.
(I've seen this in another clue)
'slow orwellian nurse' is the wordplay.
I cannot really understand how this works, but
'nurse' could be 'en' (abbreviation for state-enrolled nurse) and 'en' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for unfasten that I've seen before include "Let go" , "tie? No" , "Unlock" , "Nun's fate (anag.)" , "Undo" .)
