Scar is sort of orange (5)
I believe the answer is:
navel
This clue is a double definition.
'scar' is the first definition.
(the scar formed after cutting the umbilical cord)
'is sort of orange' is the second definition.
(navel orange is a type of orange)
(Other definitions for navel that I've seen before include "Umbilicus" , "Central point" , "Bellybutton" , "Belly button" , "Where the umbilical cord was once attached" .)
