Leaves item of jewellery to change hands (6)
I believe the answer is:
rocket
'leaves' is the definition.
(I know that Rocket is a type of leaf vegetable)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rocket that I've seen before include "that should take off?" , "One's fired up" , "A slangy reprimand or a firework" , "Firework and salad ingredient" , "Salad plant; strong reprimand" .)
