So, what do you guys here think about my alternative interpretation of the Croatian Toponyms? http://flatassembler.000webhostapp.com/toponyms.html I don't think that knowledge of the Croatian language is required to evaluate my theories, but the knowledge of linguistics is.
In short, although Croatian is a Slavic language, I think there aren't that many Slavic toponyms in Croatia, because, if there were, they would make sense to those who speak Croatian, and most of them don't. So, I try to reconstruct the language of the ancient Croatian toponyms (the Illyrian language) and explain the toponyms using it. I mostly refer to Indo-European roots (and suppose a series of sound changes that occurred from Proto-Indo-European to Illyrian), though I explain a few toponyms by claiming that some repeating elements (with definite meanings) were borrowed into Illyrian from a Pre-Indo-European language.
