Present doctrine reworked to impress university (9)
I believe the answer is:
introduce
'present' is the definition.
(I know that present can be written as introduce)
'doctrine reworked to impress university' is the wordplay.
'reworked' indicates an anagram.
'to impress' means one lot of letters goes inside another (impress can mean enlist or recruit).
'university' becomes 'u' (abbreviation for university).
'doctrine' with letters rearranged gives 'introdce'.
'introdce' enclosing 'u' is 'INTRODUCE'.
(Other definitions for introduce that I've seen before include "Provide an opening announcement for" , "Do the honours" , "Inaugurate, initiate" , "Bring in something or someone new" , "Usher in" .)
