Breathe fire (7)
I believe the answer is:
inspire
I believe this is a double definition.
'breathe' is the first definition.
(I know that inspire is a type of breathe)
'fire' is the second definition.
(I know that inspire is a type of excite)
(Other definitions for inspire that I've seen before include "Motivate" , "Influence" , "Give (feeling of) creativity to" , "Bring about; animate" , "Galvanize" .)
