Orange part of the body? (5)
I believe the answer is:
navel
This clue is a double definition.
'orange' is the first definition.
(navel orange is a kind of orange)
'part of the body?' is the second definition.
(I know that navel is part of abdomen)
(Other definitions for navel that I've seen before include "Umbilicus" , "for contemplation" , "regarded with complacency" , "Target of gaze" , "Belly button" .)
