Show priest over University College at last (5)
I believe the answer is:
revue
'show' is the definition.
(revue is a kind of show)
'priest over university college at last' is the wordplay.
'priest' becomes 'rev' (**).
'over' means one lot of letters go next to another.
'university' becomes 'u'.
'at last' suggests the final letters.
The last letter of 'college' is 'e'.
'rev'+'u'+'e'='REVUE'
(Other definitions for revue that I've seen before include "Theatrical show" , "Form of light entertainment" , "Show of sketches, songs, etc" , "Variety show with mixed entertainments" , "(Of butter) tasting off" .)
