Break in play when vile rant is broadcast (8)
I believe the answer is:
interval
'break in play' is the definition.
'interval' can be an answer for 'break' (I've seen this before). I'm not sure about the 'in play' bit.
'vile rant is broadcast' is the wordplay.
'is broadcast' indicates anagramming the letters.
'vile'+'rant'='vilerant'
'vilerant' with letters rearranged gives 'INTERVAL'.
'when' is the link.
Can you help me to learn more?
(Other definitions for interval that I've seen before include "Time to read programme notes, perhaps" , "Space of time" , "Hiatus" , "Pause (between acts)" , "Travel in (anag.)" .)
