So this is a perfect example of how things could be better-explained to the average developer via analogy:

"You can think of a type constructor like a generic type, particularly the way those work in languages like TypeScript"

Edit: The C example was added after my initial comment, and is better than nothing, though I'd tend to say the pointer example is a bit of a weird one to go with. Of course intuitiveness is relative and I'm not saying an example has to mention TypeScript or whatever to be valid. But I do think, like, C++ templates would be a somewhat clearer comparison to make for that audience.
