Where porridge tasted by European, but not an egg, say (4,4)
I believe the answer is:
germ cell
'where porridge tasted' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'european but not an egg say' is the wordplay.
'european' becomes 'German ' (Germany is in Europe).
'but not' is a deletion indicator.
'egg say' becomes 'cell' (egg is a kind of cell).
'german' with 'an' taken out is 'germ'.
'germ'+'cell'='GERM-CELL'
'by' is the link.
Can you help me to learn more?
(Other definitions for germ cell that I've seen before include "One needed to start baby" , "has possibilities of development" , "biological unit" , "potentially new life" .)
