Greta, bin emptier? (5)
I believe the answer is:
garbo
'greta' is the definition.
(Greta Garbo)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for garbo that I've seen before include "Famous film actress" , "Swedish actress born Greta Gustafsson" , "She sought solitude" , "Old film actress" , "Greta . . . . ., film star who wanted to be alone" .)
