Stir up, start burning (6)
I believe the answer is:
kindle
I believe this is a double definition.
'stir up' is the first definition.
(I've seen this in another clue)
'start burning' is the second definition.
(I've seen this before)
(Other definitions for kindle that I've seen before include "Exclamation, shout" , "Make something start burning" , "Linked (anag)" , "Light (fire)" , "E-book device" .)
