Name of Austria - Wikipedia
The Czech
and Slovak
languages have a peculiar name for Austria. Czech Rakousko
and Slovak Rakúsko neither derived from German Österreich nor from Latin Austria. The Czech name of Rakousko, previously also Rakúsy and later Rakousy, which is still used for the states of Upper
and Lower Austria
(Horní, Dolní Rakousy), originates in the name of the Austrian castle and town of Raabs an der Thaya
near the Czech-Austrian border, formerly also known as Ratgoz or Ratgos.
