Ruffian running wild in place of entertainment (7)
I believe the answer is:
funfair
'place of entertainment' is the definition.
'funfair' can be an answer for 'entertainment' (I've seen this before). I am not certain of the 'place of' bit.
'ruffian running wild' is the wordplay.
'running wild' indicates anagramming the letters.
'ruffian' is an anagram of 'FUNFAIR'.
'in' is the link.
Can you help me to learn more?
(Other definitions for funfair that I've seen before include "place of amusement" , "entertainment for the family?" , "Amusement park" , "Swings and roundabouts" , "Amusements here" .)
