So, languages I am learning and how:
German (C1 fluency and slipping)
I took 6 months of German before I moved to germany in a traditional classroom, and then I moved to Berlin in 2012 and tested (barely) C1 business fluency before I left after 6 months of 3 hours * 5 days a week of german classes plus complete immersion in everyday life.
I now keep it up, barely, by talking to german friends in DM and text, following german speaking YouTubers, doing Duolingo every day, listening to german news podcast every day, and sometimes watching german shows.
I am great at vocab, awful at grammar. Getting worse and worse at speaking by the day with no one to speak to. I pretty much cannot understand someone with a strong Bavarian accent because I learned in Berlin.
French (a3)
I took this in school for 5 years as a kid and 1 year as an adult. I can listen to basic stuff, navigate a train station and airport, say basic sentences, get the jist of what I am reading. I am only do Duolingo for this, and it shows in my poor retention
Croatian (A1)
I am working on my Croatian heritage citzenship, so I am trying to learn this.
This is the free online course for learning Croatian from Croticum for A1/A2 https://a1.ffzg.unizg.hr/
It is VERY VERY Hard to find Croatian learning as the language is relatively new (30 years since it was considered a separate language from Serbian and Bosnian) and only spoken by one small country.
I am considering taking this course from University of Zagreb March of next year, which is a combo of e-learning and skype sessions but it is 500 Euro http://www.unizg.hr/homepage/learn-croatian/e-learning-course-of-croatian
Arabic (baby)
I am learning this using Duolingo starting a few months ago.
I used ann Apple app called “Arabic Script” just for the alphabet and it was VERY helpful because Duolingo threw me in the deep end. Also it has pronunciations from three different regional/variation speakers which was helpful. I also follow a youtuber who uses Arabic so I understand some of the words by sound.
Spanish (kitchen and travel only)
Had a Mexican exchange student for a year when I was a kid, never took it in school, but between that and American pop culture/years of working in kitchens, I’m decent at Commercial Kitchen Spanish (Behind you! Hot!) and I was able to navigate and order food and tequila when I was at a conference in Guadalajara.
Russian (alphabet and skating only)
Tried to learn this due to knowing many Russian speakers at the skating rink and also because I love it for travel, I got through the alphabet and basic “I” “You” sentences, did not keep it up, made my brain hurt trying to do it with Arabic and and I gave up. Mostly used duolingo.
