What is Old Danish?

Old Danish was a language spoken in Denmark from year 800 to 1525. It represents the middle stages between Old East Norse (language of the Vikings) and modern Danish.

Old Danish can further be divided into:

  • - Runic Danish 800 - 1100 (olddansk in Danish)
  • - Early Middle Danish 1100 - 1350 (yngre gammeldansk/middeldansk in Danish)
  • - Late Middle Danish 1350 - 1525 (ældre gammeldansk/middeldansk in Danish)

A sample of Old Danish:

Takær bondæ annær man mæth sin kunæ oc kumar swa at han dræpær anti mannen [...]


If a peasant finds another man with his wife and it happens that he does not kill the man [...]

- Excerpt from The Zealandic Law of Erik, 13th century.

Written language of the dictionary

The dictionary was published in the late 1800's, making the language of the definitions quite old fashioned for readers of modern Danish. The definitions generally also contain quotes from older dictionaries, so the language can be an exotic mixture of medieval and modern Danish.

This dictionary has been machine generated, which means there are many mistakes. It is based on scans and photos of a quite large book from the 19th century. This means only a fraction of the OCR (image to text) output has been proofread.
