Abraham's city (7)
I believe the answer is:
lincoln
This clue could be a double definition.
'abraham's' is the first definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'city' is the second definition.
(Lincoln is an English city)
Can you help me to learn more?
(Other definitions for lincoln that I've seen before include "English cathedral city - US president" , "16th President of the United States" , "Former US president" , "theatre casualty" , "US president who gave Gettysburg Address" .)
