Christmas symbol offering no initial passion (5)
I believe the answer is:
anger
'passion' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for anger that I've seen before include "Wrath; annoy" , "Irateness" , "wind up?" , "Strong displeasure" , "There's fury" .)
