Yes, '';1 is a noun, but having a noun changes <;.1 completely:
<;.1 i.3 3
executes the MONAD <;.1, which behaves according to its rules.
('';1) <;.1 i.3 3
executes the DYAD <;.1 which behaves according to its rules, which are
totally different (though somewhat similar in this case).
Every verb can be invoked as a monad or a dyad, depending on whether
there is a noun to its left. You should think of the two valences as
being different verbs.

I'm new to J and am struggling to figure out why this works.
'';1 just looks like a noun:
'';1
┌┬─┐
││1│
└┴─┘
<;.1 i.3 3
┌─────┐
│0 1 2│
│3 4 5│
│6 7 8│
└─────┘
thanks for any help,

Can you write boxcols?
Can you write it tacitly without using a hook, fork, compose, or appose?
