Disney's film business doubled (4)
I believe the answer is:
coco
'disney's film' is the definition.
I can't judge whether this definition defines the answer.
'business doubled' is the wordplay.
'business' becomes 'co' (short for company).
'doubled' shows that letters should be duplicated.
'co' doubled is 'COCO'.
Can you help me to learn more?
(Other definitions for coco that I've seen before include "address for Chanel" , "French fashion designer, who branched into perfume etc" , "Famous clown" , "'... the Clown, ... Chanel (4)'" , "Gabrielle Bonheur Chanel" .)
