Magnify general confusion (7)
I believe the answer is:
enlarge
'magnify' is the definition.
(I know that magnify is a more specific form of enlarge)
'general confusion' is the wordplay.
'confusion' is an anagram indicator.
'general' is an anagram of 'ENLARGE'.
(Other definitions for enlarge that I've seen before include "Lengthen" , "Broaden, increase" , "Stretch" , "Describe in more detail" , "swell?" .)
