I would like you to describe how you create place names, be it towns, mountains, rivers or natural features. Do you invent them as nice-sounding words fitting your language, rigorously etymologically derive them or use a random word generator? What effect does the language of your country have on the place names? Do you have a dictionary for the most important toponyms or at least know these components by heart?
I use a mixed etymological-aesthetical approach when creating place names. I know the most important Germanic, Slavic and Finno-Uguric toponymic roots and use them, but I also sometimes just make up interesting or funny-sounding names from scratch, reflecting the fact that many modern place names in the real world can not be etymologically traced anymore.
