Blow up general in conflict (7)
I believe the answer is:
enlarge
'blow up' is the definition.
('enlarge' can be a synonym of 'blow up')
'general in conflict' is the wordplay.
'in conflict' indicates an anagram (I've seen this in other clues).
'general' anagrammed gives 'ENLARGE'.
(Other definitions for enlarge that I've seen before include "Dilate" , "Blow up" , "go into greater detail" , "Expand" , "Describe in more detail" .)
