Sphinx, in part (4)
I believe the answer is:
lion
'sphinx in part' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lion that I've seen before include "King of the forest" , "The -, the Witch and the Wardrobe" , "Big cat with pride" , "Large cat; rugby player" , "British RU cap" .)
