Description of Rupert Murdoch brought up in explicit opening (7)
I believe the answer is:
nepotic
'description of rupert murdoch brought' is the definition.
I can't judge whether this defines the answer.
'up in explicit opening' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'in' indicates a hidden word.
'citopen' is hidden in the letters of 'explicit opening'.
'citopen' backwards is 'NEPOTIC'.
Can you help me to learn more?
(Other definitions for nepotic that I've seen before include "tending to favour family" , "Nice pot (anag.)" , "Advancing relatives" , "showing favouritism" , "not looking beyond the family?" .)
