Rushes and scans broadcasts (5)
I believe the answer is:
reeds
'rushes' is the definition.
(I've seen this in another clue)
'scans broadcasts' is the wordplay.
'scans' becomes 'reads' ('read' can be a synonym of 'scan').
'broadcasts' indicates a 'sounds like' (homophone) clue (I've seen 'broadcast' mean this (how the word might sound on the radio or TV)).
'reads' is a homophone of 'REEDS'.
'and' is the link.
(Other definitions for reeds that I've seen before include "Tall stiff marsh grasses" , "Waterside plants" , "pens for sheep" , "Tall grasses with hollow stems" , "Tall riverside grasses" .)
