Agitation or tumult (7)
I believe the answer is:
turmoil
This clue is a double definition.
'agitation' is the first definition.
(turmoil is a kind of agitation)
'tumult' is the second definition.
(I know that tumult can be written as turmoil)
(Other definitions for turmoil that I've seen before include "Unrest - upheaval" , "Hubbub" , "Brouhaha" , "Violent commotion" , "State of great commotion or disturbance" .)
