Centres for homemade fabrics beyond development stage (6)
I believe the answer is:
embryo
'stage' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for embryo that I've seen before include "Primitive state" , "Animal in early stage, before birth" , "Early stage of fetus" , "Beginning of growth" , "Organism at early stage" .)
