Invested in university, died outside it (6)
I believe the answer is:
endued
'invested' is the definition.
('endue' can be a synonym of 'invest')
'university died outside it' is the wordplay.
I cannot really understand how this works, but
'university' could be 'u' (abbreviation as in UMass) and 'u' is found in the answer.
'died' could be 'ended' (I've seen this before) and 'ended' is found in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Another definition for endued that I've seen is " put on".)
