- Benrath line
In German linguistics, the Benrath line (German: "Benrather Linie") is the "maken-machen"
isogloss . It is traditionally used to distinguish the High German varieties from the otherWest Germanic languages . The Line runs from Benrath (part ofDüsseldorf ) andAachen to easternGermany near Frankfurt an der Oder in the area ofBerlin andDessau .The
High German consonant shift (3rd to 9th centuries AD), in the first three phases of which the Low German dialects did not participate, affected the Southern varieties of the West Germanicdialect continuum ; the Low German dialects did not participate in the first three phases (core group) of this shift. The impact of the High German consonant shift increases gradually to the South.The Benrath line does not mark the northernmost effect of the High German consonant shift, since the
Uerdingen line , the "ik-ich" isogloss, lies slightly further north; and some of the peripheral changes associated with the shift did affect Low German.External links
