Ferment, turmoil (6)
I believe the answer is:
unrest
I believe this is a double definition.
'ferment' is the first definition.
(I know that ferment can be written as unrest)
'turmoil' is the second definition.
(I've seen this in another clue)
(Other definitions for unrest that I've seen before include "Uneasiness; turmoil" , "Feeling of anxiety or turmoil" , "State of uneasiness" , "State of rebellion" , "State of agitation" .)
