Egg plants? (7)
I believe the answer is:
ovaries
'egg plants?' is the definition.
The answer and definition can be both plants as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'egg plants?' is the wordplay.
'egg' becomes 'o' (an 'o' resembles an egg).
'plants?' becomes 'varies' (I can't explain this - if you can you should give a lot more credence to this answer).
'o'+'varies'='OVARIES'
Can you help me to learn more?
(Other definitions for ovaries that I've seen before include "egg production unit" , "Egg-producing organs in female animals" .)
