One causes panic having limb stuck in a register (8)
I believe the answer is:
alarmist
'one causes panic' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'limb stuck in a register' is the wordplay.
'limb' becomes 'arm' (arm is a kind of limb).
'stuck in' means one lot of letters goes inside another.
'register' becomes 'list' (listing is a kind of registering).
'a'+'list'='alist'
'arm' placed into 'alist' is 'ALARMIST'.
'having' is the link.
Can you help me to learn more?
(Other definitions for alarmist that I've seen before include "One overstating danger" , "One may cause panic" , "One who cries wolf" , "(Person) creating unnecessary panic" , "unduly frightening" .)
