Evasive former pupil runs out of booze after leaving university (7)
I believe the answer is:
oblique
'evasive' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for oblique that I've seen before include "Slanted" , "slash" , "Backhanded" , "Slanting, indirect" , "Angled" .)
