Add fuel to (5)
I believe the answer is:
'add fuel to' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stoke that I've seen before include "Village with 'country churchyard'" , "Add coal to (a fire)" , "keep the furnace going" , "Add coal to (a furnace)" , "somewhere in the Potteries?" .)
