Just to be even clearer.

In the time of the original use, there were only static types. Languages had very little in terms of UDT's. Even a struct in C was barely a type of its own. I don't recall the details, but there was something about struct member names not being local to the struct. Interpreted languages didn't have records or classes at all(*), and certainly not types as first class objects.

We cannot really talk about how dynamically typed languages with rich type systems were originally labelled, back when they didn't exist at all.

(*) I'm looking forward to someone pointing out an interesting counterexample.
