In the
J programming language, there are two
cases for each
verb. In the
monadic case, a
verb takes 1
argument which is supplied to its
right.
That is, if x and y are nouns and v is a verb, the code ``v y'' evokes the monadic case of v; if v is a primitive, one can find its monadic and dyadic cases in the J Dictionary.
Often, the two cases of a verb are linked by some common property in their meaning.
For example:
However, one can't always depend on the cases being so tightly linked; if unsure of the meaning of a monad, run it a few times or check a reference of some sort.
