Reduced fare for long distance (3)
I believe the answer is:
far
'long distance' is the definition.
(thesaurus)
'reduced fare' is the wordplay.
'reduced' means to remove the last letter.
'fare' with its final letter removed is 'FAR'.
'for' acts as a link.
(Other definitions for far that I've seen before include "A long, long way to go" , "Remote" , "Very much" , "At a great distance way" , "Distant" .)
