These are the different series that Old Norse linguist will be happy to expand over time.
(1) The Grammar by sagas series dispenses Old Norse grammar in bite-sized chunks, based on the great texts. If the notion of grammar is new to you, you should make a point of becoming acquainted with it. Otherwise, repetition will do you a great service. Learning an ancient language is akin to learning a modern one: you forget, you relearn, until you're exhausted.
(2) There are some very good reference works on Old Norse grammar in Scandinavian languages, perhaps less so in English. The Old Norse grammar series maps out and makes accessible to the English speaker, we hope with clarity, the fundamentals of Old Norse grammar.
(3) The Norse practice series makes you read a selected passage more widely. Less intensive in grammar, more extensive in practice. Galois is convinced that languages, both ancient and modern, are learned through tireless and repeated exposure to textual data and their translation. Not just by having them run before your eyes, but by working with them, understanding them, and replaying them over and over again.
(4) Centuries of philological work have sought to shed light on the great sagas' manuscripts. Series Saga chronicles traces the authorship of the works and the circumstances of their creation, by way of the texts themselves, of course.
(5) In the Intermingling series, we indulge in our favorite exercise: the comparison, the game of seven differences, between Old Norse and other closely related languages, ancient and modern. It's about translations studies and comparative linguistics, from Old Norse to modern Scandinavian (North Germanic) languages: Norwegian, Swedish, Danish, Feroen, Icelandic; but also modern West Germanic languages: German, Dutch, English; and some of their ancestors: Old Icelandic, Old English. Here we discuss language history and geography, language sociology, idioms and dialects. We talk about archaisms and modernisms, and bridge the gap between the old and the new.
(6) In the Metapost series, as the name clearly indicates, we climb a little higher and talk about the posts themselves, i.e. the Old Norse Linguist. In shot, articles about articles. What the site includes, how it is written, how to use it. But also general, deeper topics: metaphysics and prophecies, creativity and language learning are among the themes that belong to this series. The generalist post you are reading right now is a metapost.
(7) Last but not least, the Fellow Skáld series invites specialists to contribute on their favorite subjects, in the very old-school format of the written interview. Here we encounter linguists of Old Norse, or Germanic languages, or ancient languages, specialists in language learning, masters in the realm of archives, orchestrators of cultural affairs, and even natural and computer scientists.
Be regular, and above all, make good use of your time: less mindless bureaucracy, more Old Norse.
