Plot to strike and create pandemonium (6)
I believe the answer is:
bedlam
'pandemonium' is the definition.
(I know that pandemonium can be written as bedlam)
'plot to strike' is the wordplay.
'plot' becomes 'bed' (a plot of land).
'to strike' becomes 'lam' (to 'lam' means to hit hard).
'bed'+'lam'='BEDLAM'
'and create' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for bedlam that I've seen before include "Blamed for a lot of noise" , "Scene of uproar and confusion" , "chaotic state" , "Mayhem" , "State of extreme confusion and uproar" .)
