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