There is a base class (class, which allocates one cell for the
object pointer) plus seven other words: to define a method, a variable,
a class; to end a class, to resolve binding, to allocate an object and
to compile a class method.

object is the base class of all objects.
method m v "name" – m' v mini-oof “method”
Define a selector.
var m v size "name" – m v' mini-oof “var”
Define a variable with size bytes.
class class – class selectors vars mini-oof “class”
Start the definition of a class.
end-class class selectors vars "name" – mini-oof “end-class”
End the definition of a class.
defines xt class "name" – mini-oof “defines”
Bind xt to the selector name in class class.
new class – o mini-oof “new”
