British liner rebuilt in city (6)
I believe the answer is:
berlin
'city' is the definition.
(Berlin is an example)
'british liner rebuilt in' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'rebuilt' is an anagram indicator.
'in' indicates putting letters inside.
'liner' with letters rearranged gives 'erlin'.
'b' going inside 'erlin' is 'BERLIN'.
(Other definitions for berlin that I've seen before include "Capital of Germany" , "Irving -, Russian-born musical composer" , "Composer of White Christmas" , "2 [PHILOSOPHER]" , "A once-divided city" .)
