Jars in fireplaces (6)
I believe the answer is:
grates
This clue might be a double definition.
'jars' is the first definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'fireplaces' is the second definition.
(I've seen this in another clue)
'in' is the link.
Can you help me to learn more?
(Other definitions for grates that I've seen before include "Rubs harshly against, perhaps on nerves" , "Makes harsh sound by rubbing" , "Rasps against, food or nerves" , "Makes harsh noise by rubbing - on nerves?" , "Makes rasping sound, hard on ear" .)
