Sent by air (5)
I believe the answer is:
blown
'sent by air' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for blown that I've seen before include "freely spent" , "Whistle should be" , "squandered" , "Like brass" , "(Rose) in blossom; (cover) exposed" .)
