Garden in East End requires work (4)
I believe the answer is:
eden
'garden' is the definition.
(Garden of Eden in the Bible)
'east end requires work' is the wordplay.
I cannot quite understand how this works, but
'east' could be 'e' (abbreviation) and 'e' is found in the answer.
an anagram of 'end' is 'den' which is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for eden that I've seen before include "Genesis location" , "at Number Ten once?" , "Someone once seen in Number Ten's" , "happy state" , "Anthony ---, PM 1955" .)
