I’ve been learning Icelandic on and off for about about a year - for English speakers the grammar is a bit daunting but I can understand the gist of written Icelandic now and I’m hoping when I visit this year I’ll be able to have some conversations if I can overcome my stereotypical British fear of talking in a language other than English!
Free resources I’ve used
The YouTube channel “Icelandic for Foreigners” has lots of videos about grammar. Start with the pronunciation ones for each letter. The others are handy when you know a bit more about the language.
The University of Iceland has free online courses - search for “Icelandic Online”. These are all in Icelandic but do listening, reading and writing up to an advanced level. Took me a few goes to get started with them but they are useful.
A lecturer who has taught Icelandic in the UK recorded tutorials and you can listen to the mp3s. search for “Alaric Hall Icelandic” and his website should come up. There is also a link to the language site Memrise where Alaric has put the vocabulary from the recordings. I found these great as you’re learning in real time with Rachael and Ben!
I also did some other courses on Memrise for vocab but there isn’t much audio and I’ve just started using the Drops language app as it does have audio and quite a lot of vocab and short phrase content. Although you can only do 5 minutes per day free so I bought a year pass (about $35 USD)
Gjörðu svo vel as they say in Iceland!
