My understanding is that a literal type is spec

Answer 1

Is my understanding (if not my explanation) correct for the most part?

I do not agree in one point: A literal is some kind of compile time constant (as "Hello World", 5 or 'A'). However, there are no "Literal-Types"; the literal always is the actual value.

Primitive types are IMO "basic" types like string, int, double, float, short, ...

So primitive have their types of literals connected with them.
