Some avoid arguments raised in broadcast (5)
I believe the answer is:
radio
'broadcast' is the definition.
(radio broadcast is a kind of broadcast)
'some avoid arguments raised' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'raised' shows that the letters should be reversed in order.
'oidar' can be found hidden inside 'avoid arguments'.
'oidar' back-to-front is 'RADIO'.
'in' acts as a link.
(Other definitions for radio that I've seen before include "Communications medium" , "Contact" , "Electronic medium of communication" , "Communicate with" , "Broadcast receiver" .)
