The vocabulary should not say
u&v y -> ([: u v y)"v
because
[: verb verb NOUN
is a domain error.

Here's a sentence that I think would be more helpful in the vocabulary:
]A=:'one';'two';'three'
???????????????
?one?two?three?
???????????????
#&>A
3 3 5
([:#>)">A
3 3 5
^
NB. Then shouldn't the vocabulary say u&v y -> ([: u v y)"v
