Do monkeys have a box of them? (6)
I believe the answer is:
tricks
'do monkeys' is the definition.
Although both the answer and definition are verbs in their -s form, I can't see how one could define the other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tricks that I've seen before include "Deceptions or illusions as by stage magician" , "Box of ---, ingenious device" , "Ruses ("how's ____?")" , "Illusions or strategems" , "Deceptions at the card table." .)
