Go to pieces after being dismissed in disturbance (8)
I believe the answer is:
outbreak
'disturbance' is the definition.
(I've seen this before)
'go to pieces after being dismissed' is the wordplay.
'go to pieces' becomes 'break' (I can't explain this - if you can you should believe this answer much more).
'after' says to put letters next to each other.
'being dismissed' becomes 'out' (dismissed in cricket).
'break' put after 'out' is 'OUTBREAK'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for outbreak that I've seen before include "Violent occurrence" , "Sudden spontaneous occurrence" , "Eruption of e.g. disease" , "Sudden onset (of war, disease, etc)" , "rash" .)
