Duolingo will teach you Klingon and High Valyrian, but not the national language of Luxembourg. Checked 12 August 2026: the Duolingo course list contains no Luxembourgish course for any base language, and we found no announcement of one.
If you have been keeping a streak warm while waiting for the owl to add it, this page is the honest answer: why the course is missing, what genuinely fills the gap today, and the point where an exam specific tool takes over.
There is no Duolingo course for Luxembourgish. The free official platform LLO.LU exists, works, and costs nothing. Point your daily habit there instead of waiting.
What the check covered
Because "just wait, it is coming" rumours circulate every year, here is exactly what stands behind that date. We went through Duolingo's public course list, which pairs every course with a base language, and looked for Luxembourgish in any pairing. It is not there, and no course carries the language's code. Nothing in Duolingo's public announcements mentions one either, as far as we could find.
Absence today is not a promise about next year, which is why the date matters. If you are reading this long after August 2026, spend thirty seconds on the course list before taking our word for it.
Why the gap persists
Duolingo has said nothing public about Luxembourgish in particular, so nobody outside the company can give you the reason. Two documented facts draw its shape.
First, the volunteer door closed. Small language courses once reached Duolingo through its volunteer contributor programme. The company ended that programme in 2021 and wrote that it would "pay for the creation of all course content" from then on. A Luxembourgish course now requires Duolingo to decide, internally, that building one is worth it.
Second, the audience is small by app standards. In Luxembourg's 2021 census, 275,361 residents named Luxembourgish as their main language, 48.9 percent of those counted, per Statec figures reproduced in the government's About Languages in Luxembourg brochure. The same brochure notes that main language counts cannot capture everyone who speaks it, but even a generous reading leaves an audience closer to one mid size city than to the markets a giant builds courses for.
One development cuts the other way: in April 2025 Duolingo launched 148 courses built with generative AI, so the cost of adding a language has fallen. That makes a Luxembourgish course cheaper to build than it was, and still nobody has announced one.
Neither fact says never. Both say: do not plan your Luxembourgish around a course that does not exist.
What exists instead
The strongest option is the official one. LLO.LU is the platform the state built: free, made by the Institut national des langues Luxembourg (INLL) together with the Ministry of Education, covering levels A1 through B2 with a level test to place you. It once shipped as a mobile app; its site now says it runs only in the browser, so save it to your home screen instead.
Around it sits a small, real ecosystem. Every line below was checked on the same date, 12 August 2026.
| Resource | What it is | Status at the check |
|---|---|---|
| LLO.LU | The free official platform, A1 to B2, with a level test | Active, browser only |
| INLL | In person language courses, plus Poterkëscht, a podcast for beginners | Active |
| lod.lu | The Lëtzebuerger Online Dictionnaire, the dictionary you will use weekly | Active |
| QuattroPole | Free e-learning financed by the City of Luxembourg | Offline for revision |
| uTalk | A general app with a Luxembourgish pack of more than 2,500 words and phrases | Active |
| Memrise | A general app: no official Luxembourgish course, only word lists made by other learners | No official course |
How these compare, and where each one stops, is laid out in the best apps to learn Luxembourgish.
Your streak habit transfers
Here is the quiet upside. Duolingo's real gift to you was never a specific language. It was the habit: a small session, every day, small enough that you never skipped. That habit is portable, and it is the single best thing you can carry into Luxembourgish.
LLO.LU takes the handoff well. Its chapters break into videos, short explanations and exercises, so fifteen focused minutes a day fits it the same way a lesson streak did. Same routine, different destination. The only thing you lose is the owl's guilt trips.
If you want a shape for the first week, keep it boring. Take the level test on day one and accept where it places you. Days two to six, one chapter chunk a day, always out loud, because Luxembourgish lives in your mouth, not your eyes. Day seven, go back over the words that refused to stick. Repeat the week until the level test says otherwise. Boring is what streaks are made of, and you already know how to do boring daily practice. That is the skill Duolingo gave you.
When an exam tool takes over
If Luxembourgish is curiosity or courtesy, the free platform covers you, and you can stop reading here.
If the reason is Luxembourg nationality, there is a specific exam at the end of the road: the Sproochentest, run by the INLL, with a 10 minute speaking test graded at level A2 and a 35 minute listening test at B1. Speaking is the half that decides most outcomes, because at least 50 percent there passes you outright, and a weaker speaking score only survives if your two results average to 50. What that requirement involves is its own subject, and learning the language is not the same work as rehearsing that format under a clock.
That second job is what LëtzPass, our own app, is built for: Sproochentest mock exams and speaking practice that comes back graded. It earns its place once you can hold a short conversation, not before. Until then, LLO.LU is the better use of your time, and the free mock exam will tell you when you are ready for more.
Do this next
Open LLO.LU tonight, take its level test, and move your daily fifteen minutes there this week. The streak you built waiting for Duolingo is worth more than the course you were waiting for.
