"This other ____, demi-paradise” (Shakespeare, Richard II) (4)
I believe the answer is:
eden
'this other demi-paradise shakespeare richard ii' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for eden that I've seen before include "Place of unspoilt beauty" , "PM 1955-56" , "Biblical garden" , "Badly need the garden" , "Paradise - ex-prime minister" .)
