Avzag is a fantastic app/site, you oogle 'avzap.app' and it should be the first thing you see. Avzag is building libraries for all of the languages of the region. These libraries feature a variety of different resources including audio and an ever expanding dictionary. Many thanks to Xӕxxon_dziglo for sharing it with us, it has certainly helped me a lot in some areas I was having difficulty with!
This site is a great place to learn about other aspects of Ossetian culture and history, in addition to some language learning links:
I've also found a couple of links to the more well-known papers on the Ossetian Language, including V. I. Abaev's seminal work:
There is also a subreddit, r/Ossetia-Alania, a small but dedicated community who share about topics related to the language and other facets of all things . There is also my own subreddit, r/CaucasusLanguages, to discuss the language but also foster connection with learners of other Caucasus Languages.
Available in the Play Store, and on Youtube; 'Ирон Чиныг' which allows you to listen to, and follow along with, stories written and read in Ossetian. Even if you are not studying, the reading is clear and pleasant to listen to, I enjoy it very much.
Here is a site recommended by one of our own, https://iryston.tv/ir/, an Ossetian Media-outlet, plenty of different materials to expose you to everyday Ossetian, as opposed to the often stuffy writing of academic literature.
Complimenting the Iryston website is the Iryston Youtube Channel, it offers an extensive list of playlists
with some of the playlists themselves containing videos in the hundreds. The series I am currently enjoying
I found a great flashcard style website, that includes basics such as numbers and days of the week/ months of the year.
This video is a language comparison between Modern Persian and Ossetian, they also talk a little bit about the etymology. Enjoy!
This video goes with the video directly above, as it includes one of the contributors to that video, Saeed Bazkhaneh, it also features an Ossetian speaker, Timur Chibirov, who shares some incredibly fascinating information. The balance between the two gives an excellent snapshot of Ossetian within the sphere of Indo-Iranian Lanugages. There is some interesting words and concepts to learn, and several chances to hear the languages.
