Marsupial dropped at point of gestation (4)
I believe the answer is:
womb
'point of gestation' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'marsupial dropped at' is the wordplay.
'marsupial' becomes 'wombat' (wombat is a kind of marsupial).
'dropped' suggests deleting specific letters.
'wombat' with 'at' taken away is 'WOMB'.
Can you help me to learn more?
(Other definitions for womb that I've seen before include "Generative organ" , "Place of gestation" , "Child-bearing organ" , "Organ housing fetus" , "deep dark centre" .)
