Sweet tango dancing around university (6)
I believe the answer is:
nougat
'sweet' is the definition.
(nougat is a kind of sweet)
'tango dancing around university' is the wordplay.
'dancing' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'university' becomes 'u'.
'tango' is an anagram of 'nogat'.
'nogat' placed around 'u' is 'NOUGAT'.
(Other definitions for nougat that I've seen before include "Chewy confection with nuts, cherries" , "French confection" , "Chewy sweet made of egg-white, nuts and sugar" , "Chewy nutty sweet" , "Chewy sweetmeat" .)
