Primitive tokens, since they have a fixed value, always have a role that matches their type. They're functions by default, as the modifiers have glyphs that fit specific patterns. 1-modifiers have superscript glyphs, and 2-modifiers have glyphs with an unbroken circle—that is, one without a line through it, excluding functions ⌽ and ⍉.

Variable names can be written in any case and with underscores added, and these changes don't affect what identifier the name refers to. ab, aB, AB, and _a_B_ are all the same variable. However, the spelling—specifically the first and last characters—determine the variable's role. A lowercase first letter indicates a subject, and an uppercase first letter makes it a function. A leading underscore (regardless of the following character) indicates a 1-modifier, and both leading and trailing underscores makes a 2-modifier.

Variable names (including namespace fields) can be written in any case and with underscores added, and these changes don't affect what identifier the name refers to. ab, aB, AB, and _a_B_ are all the same variable. However, the spelling—specifically the first and last characters—determine the variable's role. A lowercase first letter indicates a subject, and an uppercase first letter makes it a function. A leading underscore (regardless of the following character) indicates a 1-modifier, and both leading and trailing underscores makes a 2-modifier.

Besides these, character, string, and array literals always have a subject role, and the role of a block is determined by its type, which depends either on the header it has or which special variables it uses. If headerless, a block is a subject if it has no special names, but a 𝕨 or 𝕩 makes it at least a function, an 𝔽 makes it a 1- or 2-modifier, and a 𝔾 always makes it a 2-modifier.

The role of a compound expression, formed by applying an operation to some inputs, depends on the operation applied. This system is covered in the remaining sections below.
