Born in endless poverty (3)
I believe the answer is:
nee
'born' is the definition.
('nee' is 'born' in French)
'endless poverty' is the wordplay.
'endless' means to remove the last letter.
'poverty' becomes 'need' (need is a kind of poverty).
'need' with its last letter taken away is 'NEE'.
'in' is the link.
(Other definitions for nee that I've seen before include "Originally called" , "(Of married woman) born (with name)" , "Name originally" , "Used to show a married woman's single name" , "Born in Paris" .)
