Prepared to be feathered (6)
I believe the answer is:
tarred
This could be a double definition.
'prepared' is the first definition.
Although both the answer and definition are past participle verbs, I cannot see how one could define the other.
'feathered' is the second definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'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" .)
