Uproar about student love affair (7)
I believe the answer is:
clamour
'uproar' is the definition.
(I've seen this before)
'about student love affair' is the wordplay.
'about' becomes 'c' (abbreviation for 'circa').
'student' becomes 'l' (as in L-plates for learner drivers).
'love affair' becomes 'amour' (I've seen this before).
'c'+'l'+'amour'='CLAMOUR'
(Other definitions for clamour that I've seen before include "row" , "Uproar" , "Loud confused noise" , "Hue and cry" , "Complaints" .)
