What English word would you use to describe a particular example of a type constructor, in the sense that `List[Int]` and `List[String]` are examples of `List`s? I'd like to avoid calling them "examples" if possible.

you seem to have already settled, but I'd have gone with "materialisation" (which is I suppose just reification but with a less fancy name)

I actually didn't really consider reification, and should have! I don't think it was clear in any way from my question, but in my particular usage, I didn't want the word to focus too much on how the type came into being, because that requires understand of type constructors...

... rather, I wanted a way of relating the different reifications (incarnations) of List to each other, in a way that acknowledges they (obviously) have similarities.
