Standard English" is the literary dialect used in formal writing and in the speech of well educated persons. It descends from the West Saxon dialect of Old English, specifically the dialect of London.

There is another literary dialect called Scots ( or Lallands or Doric ) which is considered non-standard because descends from the Anglic dialect of Old English, not the Saxon.
