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.
