Born in Nine Elms (3)
I believe the answer is:
nee
'born' is the definition.
('nee' is 'born' in French)
'in nine elms' is the wordplay.
'in' indicates a hidden word.
'NEE' can be found hidden inside 'nine elms'.
(Other definitions for nee that I've seen before include "Prefix indicating maiden name of married woman" , "Adjective used to give woman's maiden name" , "called before wedding?" , "Surnamed at birth" , "Prefix to married woman's maiden name" .)
