Ariel, we hear, is a part for broadcasting (6)
I believe the answer is:
aerial
'part for broadcasting' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'ariel we hear' is the wordplay.
'we hear' indicates a 'sounds like' (homophone) clue.
'ariel' is a homophone of 'AERIAL'.
'is a' acts as a link.
Can you help me to learn more?
(Other definitions for aerial that I've seen before include "Device to receive or transmit radio waves" , "It receives radio and TV signals" , "Antenna; of the air" , "Structure to transmit or receive electromagnetic waves" , "Signal receiver" .)
