Bird swooped down (4)
I believe the answer is:
dove
This could be a double definition.
'bird' is the first definition.
(dove is a kind of bird)
'swooped down' is the second definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for dove that I've seen before include "Bird[s]" , "Bird representing peace" , "Pigeon-like bird" , "Peaceful type" , "Small pigeon" .)
