A primitive is a built-in function or operator which is a core part of the language. It is represented by a glyph, which it may share with another primitive. Special syntax like Assignment (<syntaxhighlight lang=apl inline>←</source>) and Branch (<syntaxhighlight lang=apl inline>→</source>) can also be considered primitives, though they do not abide by APL's regular syntax. Similarly, special constants like Zilde (<syntaxhighlight lang=apl inline>⍬</source>) and Dyalog APL's Root namespace (<syntaxhighlight lang=apl inline>#</source>) are sometimes called primitives.
