In Austrian German,
- "einhin" and
- "einher"
are used, but usually pronounced
- "eini" and (e.g. Er springt eini.)
- "eina" (e.g. Er springt eina.)
respectively, unless you're in the Tyrolerean Uplands where the "h" is emphasized as a fricative: "eihi" and "eiha", respectively.
Some dialects use one of the forms to express both directions, therefore not referencing the speakers location.
