Fumes with anger (7)
I believe the answer is:
incense
This clue could be a double definition.
'fumes' is the first definition.
The answer and definition can be both substances as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'anger' is the second definition.
(to incense is make angry)
'with' acts as a link.
Can you help me to learn more?
(Other definitions for incense that I've seen before include "Fragrant substance to drive to anger" , "Make angry: aromatic substance" , "can cause strong emotion" , "Grains burnt in church etc" , "Substance burnt in church" .)
