Container for jade, perhaps (8)
I believe the answer is:
horsebox
'container for jade perhaps' is the definition.
I can't judge whether this definition defines the answer.
'container for jade perhaps' is the wordplay.
'container' becomes 'box' (box is a kind of container).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'jade perhaps' becomes 'horse' (jade is a kind of horse).
'box' put after 'horse' is 'HORSEBOX'.
Can you help me to learn more?
(Other definitions for horsebox that I've seen before include "It takes animals to the races" , "road trailer" , "Animal transporter" , "Equine conveyance" , "Equine transporter" .)
