Prince William gestures audibly? They bring us a broadcast (8)
I believe the answer is:
airwaves
'audibly? they bring us a broadcast' is the definition.
The definition suggests an adverb but the answer is not.
'prince william gestures' is the wordplay.
'prince william' becomes 'air' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gestures' becomes 'waves' (wave is a kind of gesture).
'air'+'waves'='AIRWAVES'
Can you help me to learn more?
(Other definitions for airwaves that I've seen before include "Radio broadcasts across them" , "Broadcasting frequencies" , "Medium through which radio signals are transmitted" , "Means of broadcasting" .)
