C. Adverbs and Conjunctions
Unlike verbs, adverbs and conjunctions have fixed valence:
an adverb is monadic (applying to a single argument to its left),
and a conjunction is dyadic.
Conjunctions and adverbs apply to noun or verb arguments;
a conjunction may produce as many as four distinct classes of results.
For example, u&v produces a composition of the
verbs u and v; and ^&2 produces
the square by bonding the power function with the right
argument 2; and 2&^ produces the
function 2-to-the-power. The conjunction & may
therefore be referred to by different names for the different cases,
or it may be referred to by the single term and (or with),
which roughly covers all cases.
