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 the answer is hidden within the clue.
'OSCAR' is hidden within '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" .)
