No longer held fun rave with zero dancing (7)
I believe the answer is:
unfroze
'no longer held' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how one could define the other.
'fun rave with zero dancing' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'fun' is 'unf' which is present in the answer.
an anagram of 'zero' is 'roze' which is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for unfroze that I've seen before include "melted" , "Relaxed restrictions!" .)
