Old Norse Dictionary is a digital language reference project dedicated to making Old Norse vocabulary accessible to scholars, students, and enthusiasts. Based primarily on Richard Cleasby and Gudbrand Vigfusson’s dictionary, first published in 1874, it offers a searchable resource covering more than 34,000 words. Entries provide definitions, etymologies, and usage examples drawn from historical texts, helping users explore the meanings and contexts of the language.

The site includes a search tool with instant results and fuzzy matching, as well as browsing by letter and links between related terms, abbreviations, and source materials. Visitors can also consult information about Old Norse, a North Germanic language spoken in Scandinavia and its overseas settlements during the Viking Age, through about 1300. Additional resources include works and authors, abbreviations, and authentic runic inscriptions.

With support for multiple interface languages, Old Norse Dictionary combines historical scholarship with practical digital tools for discovering and studying the language
