Some amusement is loud and prejudiced (7)
I believe the answer is:
funfair
'some amusement' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for funfair that I've seen before include "Swings and roundabouts" , "entertainment for the family?" , "Amusements here" , "Amusement park" , "place of amusement" .)
