Born as integer - not odd! (3)
I believe the answer is:
nee
'born as' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nee that I've seen before include "Indicates the family name of a married woman" , "Born in France" , "Born (indicating a woman's maiden name)" , "Indicating the birth name of a married woman" , "Indicates the birth name of a married woman" .)
