Increase the general confusion (7)
I believe the answer is:
enlarge
'increase' is the definition.
(I know that enlarge is a more specific form of the action increase)
'general confusion' is the wordplay.
'confusion' is an anagram indicator.
'general' with letters rearranged gives 'ENLARGE'.
'the' is the link.
(Other definitions for enlarge that I've seen before include "Increase in size" , "Make bigger, say photo" , "Expatiate" , "Expand" , "Widen" .)
