Clamour as game cut short (6)
I believe the answer is:
racket
'clamour' is the definition.
(both can mean a loud disturbance)
'game cut short' is the wordplay.
'game' becomes 'rackets' (rackets is a racket sport).
'cut short' means to remove the last letter.
'rackets' with its last letter taken off is 'RACKET'.
'as' acts as a link.
(Other definitions for racket that I've seen before include "Clamour; tennis bat" , "Awful noise" , "Light bat" , "Swindle - uncovered in the courts" , "Lot of noise, or tennis bat" .)
