A proviso arranged about university as a layer perhaps (9)
I believe the answer is:
oviparous
'as a layer perhaps' is the definition.
(oviparous means laying eggs)
'a proviso arranged about university' is the wordplay.
'arranged' indicates an anagram.
'about' is an insertion indicator.
'university' becomes 'u' (abbreviation for university).
'a'+'proviso'='aproviso'
'aproviso' is an anagram of 'oviparos'.
'oviparos' going around 'u' is 'OVIPAROUS'.
(Other definitions for oviparous that I've seen before include "Producing eggs hatching outside the body" , "As some layers" , "Egg-laying (birds, fish or animals)" .)
