The Wurdboek fan de Fryske taal (WTF)

The Corpus of Old Dutch is the collection of all texts in Old Dutch that served as source material for the Dictionary of Old Dutch (ONW). The texts originate from the period between 475 and 1200.

Old Dutch is the collective term for several related dialects that – just like Old English, Old Frisian, Old Saxon, and Old High German – developed out of West Germanic around the beginning of the fifth century. It was spoken in an area that does not entirely correspond with the current Dutch-speaking region.

Differentiating between Old Dutch, Old Saxon, and Old Frisian is sometimes difficult.
