Clever turn-around for public transport (5)
I believe the answer is:
trams
'for public transport' is the definition.
(I've seen this before)
'clever turn' is the wordplay.
'clever' becomes 'smart' (similar in meaning).
'turn' says the letters should be written in reverse.
'smart' in reverse letter order is 'TRAMS'.
'around' is the link.
(Other definitions for trams that I've seen before include "silk yarns" , "old vehicles" , "public transport" , "Not seen in London" , "People movers" .)
