Do return to enter Lincoln residence (5)
I believe the answer is:
abode
'residence' is the definition.
(synonyms)
'do return to enter lincoln' is the wordplay.
'return' says the letters should be written in reverse.
'to enter' is an insertion indicator.
'lincoln' becomes 'abe' (Abraham Lincoln).
'do' written backwards gives 'od'.
'od' going into 'abe' is 'ABODE'.
(Other definitions for abode that I've seen before include "House made of adobe" , "Where one lives" , "Home or domicile" , "House, home" , "Place of residence" .)
