South American university wise guys making bangers! (8)
I believe the answer is:
sausages
'bangers' is the definition.
(I know this)
'south american university wise guys' is the wordplay.
'south american' becomes 'SA'.
'university' becomes 'U' (abbreviation for university).
'wise guys' becomes 'sages' (I've seen this in another clue).
'sa'+'u'+'sages'='SAUSAGES'
'making' is the link.
(Other definitions for sausages that I've seen before include "eg Hot-dogs" , "Bangers" , "Minced meat stuffed in casings" , "Minced seasoned meat stuffed in tubes" , "They may be eaten" .)
