Smoke from Magic Dragon? (4)
I believe the answer is:
puff
'smoke' is the definition.
(puffing is a kind of smoking)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for puff that I've seen before include "Smoke - light pastry" , "1 across [DRAGON]" , "Short explosive burst of breath" , "Gasp" , "Advertise" .)
