Blow up the awful general (7)
I believe the answer is:
enlarge
'blow up' is the definition.
(synonyms)
'awful general' is the wordplay.
'awful' indicates an anagram.
'general' with letters rearranged gives 'ENLARGE'.
'the' acts as a link.
(Other definitions for enlarge that I've seen before include "Dilate" , "Lengthen" , "Expatiate" , "go into greater detail" , "Make bigger in general" .)
