Broadcaster receiving reprimands for fireworks (10)
I believe the answer is:
skyrockets
'for fireworks' is the definition.
(skyrocket is a kind of firework)
'broadcaster receiving reprimands' is the wordplay.
'broadcaster' becomes 'sky' (Sky is a broadcast TV channel).
'receiving reprimands' becomes 'rockets' (I am not sure about this - if you are sure you should believe this answer much more).
'sky'+'rockets'='SKYROCKETS'
Can you help me to learn more?
(Another definition for skyrockets that I've seen is " Fireworks".)
