These are really interesting. I wonder how the relate, linguistically, with things like “Hamburger Meat” and “Tuna Fish” both of which have the addition of unnecessarily specifying to which group they belong.
It’s also an interesting conversation starter to think about which words are going to need Retronyms in the future. We already specify 3D vs 2D films, but I could see that becoming something we’d need to be even more specific about in the future. It might even become immersive vs. flat. What about books? Are we already moving into Retronym territory by having to specify print book instead of e-book?
In any case, I think it’s a fascinating look at the way we interact with the words around us.
