Part of your anatomy that's orange (5)
I believe the answer is:
navel
'that's orange' is the definition.
(navel orange is a kind of orange)
'part of your anatomy' is the wordplay.
I cannot quite see how this works, but
'part' could be 'nave' (I have seen 'Part of church ' mean 'nave' so perhaps 'part' could also mean 'nave') and 'nave' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for navel that I've seen before include "for contemplation" , "Target of gaze" , "Scar on the stomach (for gazing at?)" , "Variety of orange" , "Where the umbilical cord was once attached" .)
