Anger included feeling when deprived of leader (7)
I believe the answer is:
incense
'anger' is the definition.
(to incense is make angry)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for incense that I've seen before include "Get under someone's skin" , "It produces a fragrant odour when burnt" , "Make very angry about the fragrant smoke?" , "Rouse to anger" , "Make furious" .)
