Shake a container for arrows (6)
I believe the answer is:
quiver
'shake' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for quiver that I've seen before include "Wobble" , "Tremble and shake, or receptacle for arrows" , "Arrow-holder; shake" , "Receptacle in which archer keeps arrows" , "Arrow case" .)
