Where ignorance is bliss? (5,8)
I believe the answer is:
fools paradise
'where' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'ignorance is bliss?' is the wordplay.
'ignorance' becomes 'fools' (I can't justify this - if you can you should believe this answer much more).
'is bliss?' becomes 'paradise' (I've seen this before).
'fools'+'paradise'='FOOLS PARADISE'
Can you help me to learn more?
(Other definitions for fools paradise that I've seen before include "Ill-founded state of happiness" , "Place of happy denial" , "Illusory happiness" , "Deceptively happy state" , "Happy state while ignorant of potential trouble" .)
