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 () and Branch () can also be considered primitives, though they do not abide by APL's regular syntax. Similarly, special constants like Zilde () and Dyalog APL's Root namespace (#) are sometimes called primitives.
