Nun had ice cocktail and let loose (9)
I believe the answer is:
unchained
'loose' is the definition.
(thesaurus)
'nun had ice cocktail' is the wordplay.
'cocktail' indicates anagramming the letters.
'nun'+'had'+'ice'='nunhadice'
'nunhadice' with letters rearranged gives 'UNCHAINED'.
'and let' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for unchained that I've seen before include "Freed from shackles" , "Free" , "out of bonds?" , "like the melody in popular song" , "- - Melody (1955 hit)" .)
