Feed the fires of the Potteries (5)
I believe the answer is:
stoke
'feed' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stoke that I've seen before include "Feed with fuel" , "city" , "Add coal to (a furnace)" , "Add fuel to" , "Attend to fire" .)
