Award kept in Garbo's caravan? (5)
I believe the answer is:
oscar
'award' is the definition.
(Academy Award)
'in garbo's caravan?' is the wordplay.
'in' indicates a hidden word.
'OSCAR' is hidden in the letters of 'garbos caravan'.
'kept' is the link.
(Other definitions for oscar that I've seen before include "Man" , "Film-prize statuette" , "letter read out on radio" , "academy's prize" , "Title of Hollywood Academy award" .)
