At university, rower across river causes pandemonium (6)
I believe the answer is:
uproar
'pandemonium' is the definition.
(thesaurus)
'at university rower across river' is the wordplay.
'at university' becomes 'up'.
'rower' becomes 'oar' (I've seen this before).
'across' is an insertion indicator.
'river' becomes 'r'.
'up'+'oar'='upoar'
'upoar' placed around 'r' is 'UPROAR'.
'causes' acts as a link.
(Other definitions for uproar that I've seen before include "Din, tumult" , "Violewnt outburst of noise, pandemonium" , "Tumult, noisy ruckus" , "Loud and impassioned noise or disturbance" , "Loud group protest" .)
