Establish warped doctrine university admitted (9)
I believe the answer is:
'establish' is the definition.
(I know that introduce is a more specific form of the action establish)
'warped doctrine university admitted' is the wordplay.
'warped' indicates an anagram.
'university' becomes 'U' (abbreviation for university).
'admitted' indicates putting letters inside (inserted letters get admitted).
'doctrine' with letters rearranged gives 'introdce'.
'introdce' enclosing 'u' is 'INTRODUCE'.
(Other definitions for introduce that I've seen before include "To add" , "Bring to notice or make known" , "Bring in something or someone new" , "Do the honours" , "Bring in for the first time" .)
