Prepared to be feathered (6)
I believe the answer is:
tarred
This clue could be a double definition.
'prepared' is the first definition.
Although both the answer and definition are past participle verbs, I don't see how they can define each other.
'feathered' is the second definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for tarred that I've seen before include "in the black" , "Coated with asphalt" .)
