In Genesis a derelict property is made over to him (8)
I believe the answer is:
assignee
'made over to him' is the definition.
The definition suggests a singular noun which matches the answer.
'in genesis a derelict property' is the wordplay.
'genesis a' anagrams to 'ASSIGNEE'.
Though, I am not clear how this is indicated.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for assignee that I've seen before include "Property is transferred to him" , "One receiving property" , "One to whom legal right is transferred" , "One to whom a right or liability is transferred" , "He's given" .)
