Chop stick (6)
I believe the answer is:
I believe this is a double definition.
'chop' is the first definition.
'stick' is the second definition.
(cleave can mean to stick to something)
(Other definitions for cleave that I've seen before include "Open" , "Adhere - or chop as with axe" , "Adhere or split apart" , "Chop or stick to" , "Fissure" .)
