Commoner disregarding article in French organ (4)
I believe the answer is:
womb
'organ' is the definition.
(womb is a kind of organ)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for womb that I've seen before include "Embryo's home" , "Place of conception" , "Place of origin" , "deep dark centre" , "Organ housing fetus" .)
