Have cold feet about abdication broadcast (5)
I believe the answer is:
waver
This clue could be a double definition.
'have cold feet' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'abdication broadcast' is the second definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'about' acts as a link.
Can you help me to learn more?
(Other definitions for waver that I've seen before include "fluctuate" , "Be irresolute; flicker" , "Falter, be irresolute" , "One making signal" , "someone gesticulating wildly" .)
