Clever to get trams to return (5)
I believe the answer is:
smart
'clever' is the definition.
(similar in meaning)
'trams to return' is the wordplay.
'to return' shows that the letters should be reversed in order.
'trams' written backwards gives 'SMART'.
'to get' is the link.
(Other definitions for smart that I've seen before include "Well-dressed" , "Sting - witty" , "Brainy" , "Fashionable" , "well-kept" .)
