Perhaps it will make it easier to remember if you consider it as a
universal rule, rather than some kind of exception for conjunctions: J's
grammar would break down if any part of speech we
coprime2 =. 1:=+.
Ah, of course. I forgot about +. (I thought it was only logical or)

Its rare to forget that adverbs and conjunctions are greedy to the left. The
mistake I make regularly is forgetting that conjunctions are not greedy to the
right.

Your analysis of how that verb acts is correct, with one small exception.
Adverbs (and conjunctions) have long left scope, so =&0@:+/ isn't (=&0)@:(+/),
it's actually (=&0@:+)/ . So =&0@:+/ 1 1 1 is 1 (=&0@:+) 1 (=&0@:+) 1 .
What you want is coprime =. =&0@:(+/)@:(e.&q:) .
With that said, w
try:
coprime =. =&0@:(+/)@:(e.&q:)
the adverb / is greedy and will try and make the verb to the left as big as
possible. I.e. (=&0@:+)/ not just +/
You could also use:
coprime=: 0 = +/@:(e.&q:)

My attempt at a coprime dyadic verb, which returns 1 for coprime integers and 0
otherwise seems to not work. I do not understand why this verb fails.

My understanding is thus:

5 (e.&q:) 6
