French priest born in Lincoln (4)
I believe the answer is:
abbe
'french priest' is the definition.
(I've seen this in another clue)
'born in lincoln?' is the wordplay.
'born' becomes 'b' (common abbreviation).
'in' is an insertion indicator.
'lincoln?' becomes 'abe' (Abraham Lincoln).
'b' put inside 'abe' is 'ABBE'.
(Other definitions for abbe that I've seen before include "Leading cleric" , "one such as Liszt" , "It's a French ecclesiastic, babe" , "Continental priest" , "French abbot" .)
