What is a lexicon?

A lexicon is a structured, machine-usable repository of relevant linguistic knowledge about words in a language. A lexicon will contain historical variants (orthographical variants, inflected forms) and link them to a corresponding dictionary form in modern spelling (known as a ‘modern lemma’). In this way, a user can search for a modern word (‘water’) and receive results that take into account all historical variants in that language (‘wæter’, ‘weter’, ‘waterr’, ‘watre’, etc.)

The Impact Centre of Competence provide historical and named entities lexica for the following languages:

In addition, we offer access to the following corpora:
