Queen provided rising passion (4)
I believe the answer is:
fire
'passion' is the definition.
(fire is a kind of passion)
'queen provided rising' is the wordplay.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'rising' says the letters should be written in reverse (going up in a down clue).
'er'+'if'='erif'
'erif' in reverse letter order is 'FIRE'.
(Other definitions for fire that I've seen before include "Flames; passion" , "See 5" , "Dismiss; bake in a kiln" , "Sack; discharge (a gun)" , "Blaze - discharge" .)
