A coal-burning vessel (7)
I believe the answer is:
brazier
'vessel' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for brazier that I've seen before include "Bizarre (anag)" , "Outdoor coal or charcoal heater" , "Portable heater" , "Portable stand for coals" , "Container of burning coals" .)
