We have revised the terms in which we talk about q, to align them with common usage. You will find operators and unary and binary functions applied prefix, infix and postfix. Q’s adverbs still need their distinctive name, but you will no longer find references to verbs, monads or dyads.
We also now distinguish consistently between glyphs and what they denote. In some cases we’ve had to coin new names for what was previously conflated. So, for example,
/ denotes three adverbs: over, fold and converge-repeat.
Overloads such as these are distinguished in use by syntax and arguments. Every operator, function and adverb now has its syntax and arguments consistently and clearly described.
