more or less pure germanic
major germanic
not declareable
only minor germanic
Slavic influence in Austria (or among east germans) is very ovverrated and strongly connected to the pan-slavic propaganda. Burgenland have never been ethnic hungarian, never in the history, the real capital of Burgenland, called Ödenburg (now it's a part of Hungary) was also mostly german. Hungarians, slavs were only minority there, and the first one had tons of germanic influence (i mean genetic) just like czechs and slovenes, so it doesn't make austrians less germanic.
As stated before linguistically "germanic" means a principal branch of the Indo-European family of languages, comprising the languages descended from Proto-Germanic: it is divided into three groups
: East Germanic, (including Gothic), North Germanic, (Norwegian, Danish, Swedish, Icelandic, Old Norse, etc.), and West Germanic (English, Dutch, German, Yiddish, Frisian, etc.)
Germanic is used to describe the ancient culture and language of the peoples of northern Europe.
Following those two definitions, Austria would of course be Germanic.
