Another egg missing in reproductive part (6)
I believe the answer is:
anther
'reproductive part' is the definition.
'anther' can be an answer for 'part' (I have seen 'Part of plant ' mean 'anther' so perhaps 'part' could also mean 'anther'). I am not certain of the 'reproductive' bit.
'another egg missing' is the wordplay.
'egg' becomes 'o' (an 'o' resembles an egg).
'missing' indicates named letters should be taken away.
'another' with 'o' taken away is 'ANTHER'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for anther that I've seen before include "Pollen part of flower" , "produces pollen" , "(Actors) leave stage" , "Pollen-containing flower part found in Tehran" , "Pollen-holding part of stamen" .)
