Delete ropy misportrayal cobbled together by scaremonger (8)
I believe the answer is:
alarmist
'scaremonger' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for alarmist that I've seen before include "Creating needless worry" , "prophet of doom" , "A slim tar (anag.)" , "Given to causing unnecessary panic" , "One who worries others needlessly" .)
