Part of a hip Paris destination (5)
I believe the answer is:
ilium
'part of a hip' is the definition.
('ilium' is part of 'hip')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ilium that I've seen before include "hip (at least in part)" , "Large pelvic bone" , "Large bone of the pelvis" , "Bone; ancient Troy" , "Part of skeleton" .)
