Finish university with little finally to invest (5)
I believe the answer is:
endue
'to invest' is the definition.
('endue' can be a synonym of 'invest')
'finish university with little finally' is the wordplay.
'finish' becomes 'end' (synonyms).
'university' becomes 'u' (abbreviation for university).
'with' is a charade indicator (letters next to each other).
'finally' indicates one should take the final letters.
The last letter of 'little' is 'e'.
'end'+'u'+'e'='ENDUE'
(Other definitions for endue that I've seen before include "Furnish" , "Supply (with a quality/ability)" , "Invest - provide" , "Endow or crown with" , "Endow (poetic)" .)
