Destructive compulsion from extremists in party leading country (9)
I believe the answer is:
pyromania
'destructive compulsion' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'extremists in party leading country' is the wordplay.
'extremists in' suggests removing the centre.
'leading' means one lot of letters go next to another.
'country' becomes 'romania' (European country).
'party' with its middle taken out is 'py'.
'py'+'romania'='PYROMANIA'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for pyromania that I've seen before include "Obsessive desire to start fires" , "Obsession with burning things" , "criminal tendency" , "Flaming madness!" , "setting of conflagration" .)
