Great conclusion about getting blown up (8)
I believe the answer is:
enlarged
'blown up' is the definition.
('enlarge' can be a synonym of 'blow up')
'great conclusion about' is the wordplay.
'great' becomes 'large' (synonyms).
'conclusion' becomes 'end' (something's conclusion is its end).
'about' means one lot of letters goes inside another.
'large' inserted into 'end' is 'ENLARGED'.
'getting' acts as a link.
(Other definitions for enlarged that I've seen before include "Made bigger, say photo" , "Blew up" , "Elaborated or made bigger" , "puffed out?" , "Magnified" .)
