Austria is a federal republic made up of nine states, known in German as Länder (singular Land). Since Land is also the German word for a country, the term Bundesländer ("federated states"; singular Bundesland) is often used instead to avoid ambiguity. The Constitution of Austria uses both terms. In English, the term (Bundes)land is commonly rendered as "state" or "province".
