If a generic word is called with an object and multiple methods specialize on classes that this object is an instance of, usually the most specific method is called ( Method precedence ).

Less-specific methods can be called directly:
call-next-method


A lower-level word which the above expands into:
(call-next-method) ( method -- )


To look up the next applicable method reflectively:
next-method ( class generic -- method/f )


Errors thrown by improper calls to call-next-method:
inconsistent-next-method ( class generic -- * )

no-next-method ( method -- * )
