Eve or Mrs Biden? (5,4)
I believe the answer is:
first lady
This clue might be a double definition.
'eve' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'mrs biden?' is the second definition.
The definition suggests a singular noun which matches the answer.
'or' is the link.
Can you help me to learn more?
(Other definitions for first lady that I've seen before include "Barbara Bush or Michelle Obama?" , "Michelle Obama, for example" , "top partner" , "Title of American President's wife" , "Formerly, Jackie Kennedy for example" .)
