Endures river that is flooding Oxford University (5,3)

Ross

I believe the answer is:

rides out

'endures' is the definition.
(to ride something out is to endure it)

'river that is flooding oxford university' is the wordplay.
'river' becomes 'r'.
'that is' becomes 'idest' ('that is' in Latin).
'flooding' is an insertion indicator (some letters flood or submerge others).
'oxford university' becomes 'ou'.
'idest' placed around 'ou' is 'idesout'.
'r'+'idesout'='RIDES OUT'

(Another definition for rides out that I've seen is " Survives intact".)
