There are many widely varying names of Germany in different languages, more so than for any other European nation. For example: the German language endonym is Deutschland, from the Old High German diutisc. the French exonym is Allemagne, from the name of the Alamanni tribe. In Italian it is Germania, from the Latin Germania, although the German people are called tedeschi. in Polish it is Niemcy, from the Proto-Slavic nemets, referring to strangers, incomprehensible to Slavic speakers. the Finnish call the country Saksa, from the name of the Saxon tribe.
