Funeral fire (4)
I believe the answer is:
pyre
'funeral fire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pyre that I've seen before include "Pile of wood for burning a dead body" , "Funeral mound" , "Fire for burning corpse" , "Heap for cremating a corpse" , "Pile of wood for burning as at ancient funeral" .)
