Endure one day in Lincoln (5)
I believe the answer is:
abide
'endure' is the definition.
('abide' can be a synonym of 'endure')
'one day in lincoln' is the wordplay.
'one' becomes 'i' (Roman numeral).
'day' becomes 'd'.
'in' is an insertion indicator.
'lincoln' becomes 'abe'.
'i'+'d'='id'
'id' placed within 'abe' is 'ABIDE'.
(Other definitions for abide that I've seen before include "Stand" , "Stomach" , "brook" , "'. . . . . with me, fast falls the eventide'" , "Endure; dwell" .)
