Jar in which to put coal (5)
I believe the answer is:
grate
'jar' is the definition.
(make unpleasant sound)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for grate that I've seen before include "Jar; fireplace" , "in which Santa lands?" , "Grind, rasp" , "part of fireplace" , "Rasp; fire holder" .)
