Depression acquired at birth? (9)
I believe the answer is:
umbilicus
This might be a double definition.
'depression' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'acquired at birth?' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for umbilicus that I've seen before include "Navel" , "Something in the tummy" .)
