Former student (7)

Ross

I believe the answer is:

alumnus

'former student' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for alumnus that I've seen before include "US college old boy" , "Ex-pupil" , "Past pupil" , "Former school pupil" , "School or college graduate" .)

I've seen this clue in The Guardian, The Telegraph and The Times.
