Arrest nude in frolics being abandoned (12)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
unrestrained
'being abandoned' is the definition.
(I've seen this before)
'arrest nude in frolics' is the wordplay.
'frolics' indicates an anagram (I've seen 'frolicking' mean this).
'arrest'+'nude'+'in'='arrestnudein'
'arrestnudein' is an anagram of 'UNRESTRAINED'.
(Other definitions for unrestrained that I've seen before include "Not held back" , "Frantic" , "Unchecked" , "spreading everywhere?" , "Not restricted" .)
