Star comes back in luggage-van (4)
I believe the answer is:
vega
'star' is the definition.
(Vega is an example)
'comes back in luggage-van' is the wordplay.
'comes back' says the letters should be written backwards.
'in' indicates a hidden word.
'agev' is hidden within 'luggage van'.
'agev' back-to-front is 'VEGA'.
(Other definitions for vega that I've seen before include "Bright star of constellation Lyra" , "Gave turn to a star" , "Brightest star of constellation Lyra" , "Star in Lyra; grassy plain (Spanish)" , "heavenly body" .)
