Increase general disorder (7)
I believe the answer is:
enlarge
'increase' is the definition.
(I know that enlarge is a type of increase)
'general disorder' is the wordplay.
'disorder' is an anagram indicator (a disordered version of the letters).
'general' is an anagram of 'ENLARGE'.
(Other definitions for enlarge that I've seen before include "Dilate" , "Gleaner (anag.)" , "Broaden, increase" , "Expatiate" , "swell?" .)
