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
