It is hard to explain-it is a matter of spelling phonetically in a different language because my first language-the one I speak at least 90% of the time-is English...
There are other agglutinative languages, and many of them appear to be isolates; Sumerian, for one example, was spoken by a people who, by their own account, came into Mesopotamia by sea, then proceeded to invent a writing system (cuneiform) which was in use until sometime in late antiquity or the early Middle Ages (and then its secrets were lost for over a thousand years), in use longer than any writing system including the Chinese script. As a people they just vanished in a demographic tide, leaving behind some of their legends, and practically no geographic placenames (they used the existing names for their cities and the rivers etc). Sumerian has been suggested as the language of the Indus scripts, but I think that has been shown to be impossible. It’s possible that it hides an ancient version of Dravidian, but it’s at least as likely that it will prove to be an otherwise unknown language that is an isolate.
