Bird abandoning river afflicted with wound? (6)
I believe the answer is:
bitten
'with wound?' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bitten that I've seen before include "Once ..., twice shy, it's said" , "Attacked by, eg, an insect" , "Attacked with teeth" , "Once this, twice shy they say" , "Seized with the teeth" .)
