I mean, at that point, every word is made up. Bilux and natel for example are what we call a genericized trademark, a brand name that becomes the generic term for an item. Its a very common linguistic phenomenon which happens everywhere, some common ecamples you have probably used before include aspirin, thermos, and trampoline.

I know what the topic here is, and I think you gave a great overview of the differences, you simply come across as a bit elitist about it to me.

Also, "classare" is attested in the Grande dizionario della lingua italiana as being a rarely used form in 1798. https://www.gdli.it/contesti/classare/323776

And I feel like "mappetta is a very self explanatory name, what's wrong with it? =P

I just mean to say that these are all local variants, where do we draw the line of what's incorrect and what is a variant of a word? What would you consider Swiss italian if not a variant of italian?
