Stick in the fire (4)
I believe the answer is:
spit
'stick in the fire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for spit that I've seen before include "little light rain" , "A spade's depth, in earth" , "Large skewer - expel saliva" , "Headland, saliva" , "Narrow strip of land projecting into the sea" .)
