Primatives

[[ Language design ]] choice that is fundamental to establishing the mental model

Can be anything: scheme picture language, vectors, matrices objects.

Can be multiple, but often there is a set of primary datatypes. Some languages only have one and the result is a striking mental model for how to solve problems.

Maybe primitive is the wrong word.
