Somewhat abstracted, president ran ceremony in doorway (8)
I believe the answer is:
entrance
'doorway' is the definition.
(I've seen this in another clue)
'somewhat abstracted president ran ceremony' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'ENTRANCE' is hidden in the letters of 'abstracted president ran ceremony'.
'in' acts as a link.
(Other definitions for entrance that I've seen before include "Charm - one's way in" , "lobby?" , "Beguile" , "Gate" , "appearance" .)
