Feed, as a fire (5)
I believe the answer is:
stoke
'feed as a fire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stoke that I've seen before include "Where pottery is made" , "Village with 'country churchyard'" , "Add coal to (a fire)" , "Tend a kiln" , "Attend to fire" .)
