Right to avoid description of motorway for description of flying (6)
I believe the answer is:
aerial
'right' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for aerial that I've seen before include "Rod or antenna for receiving signals" , "Ethereal" , "Device for sending or receiving signals" , "It picks up radio waves" , "Antenna; of the air" .)
