Old English, a language originating in early medieval England and a predecessor of modern English, has some unique features that may make it difficult to study. For example, Old English uses three letters that do not exist in modern English and does not use the letters j, v, w, or z. This resource helps readers understand and read the language, with useful tools for both novice and experienced Old English learners. Readers will find a Course Index, with topical modules on nouns, verbs, syntax, and more. There is also a Pronunciation Guide, which includes notes and embedded audio. The Home page links to a beginner's guide and a brief history, great starting points for new learners. Victoria Koivisto-Kokko created Old English Online in 2018 as a component of her master's thesis at the University College Cork. Funding was provided by the UCC National Forum's "Developing Disciplinary Excellence in Learning, Teaching and Assessment" fund. Dr. Tom Birkett also contributed to the project. As a "living resource," updates and changes are constantly being added. For more information on how users can contribute to this process, check out the FAQ section.
