Classification
The ISO 639-3 code for the Bavarian language is "bar". It had no ISO 639-2 code of its own, but was classified under the "Germanic (Other)" collective language code "gem". Genetically, Bavarian is part of the Upper German family along with Alemannic (which includes Swabian and Swiss German), whereas Standard German is part of the Middle German family, closer to Upper Saxon German, which – linguistically – is a Thuringian dialect. The Bavarian word Servus (goodbye) obviously is directly from Latin.
