If German is your first language, you start the Sproochentest closer to passing than almost anyone in the room. You already hear the rhythm, and you already know half the words. The thing that trips you up is not the gap between German and Luxembourgish. It is how small that gap looks, because the small gap is where the points leak out.
Picture the interview. The examiner asks about your week. You mean to say you went to the market, and out comes Markt. You want to say the table, and you reach for Tisch. Both are clear. Both are German. The examiner is grading your Luxembourgish, so each one is a quiet miss, even when you were understood. That is the real test for a German speaker: not learning a new language, but switching off the one that wants to take over.
Your head start is real
Do not let that warning scare you off the advantage, because the advantage is large. The sentence shapes feel familiar, and word order behaves the way your ear expects. Many everyday words are shared and need no change at all: Haus, Mann, gutt. You can build a simple A2 answer in Luxembourgish faster than a French or English speaker can, because the scaffolding is already in your head.
So the work is not "start over." It is "stop translating." You are not learning grammar from zero, only catching the handful of words and the one sound rule that mark you as German rather than Luxembourgish. The topics help here too. They are predictable household talk: family, work, food, your daily routine, the things you can already think about in the right structures.
The words that give you away
These are the swaps that come up most in the interview. There are not many. Learn this short list, say them out loud, and most of your German leakage closes.
| You reach for (German) | Say (Luxembourgish) | English |
|---|---|---|
| Kartoffeln | Gromperen | potatoes |
| Tisch | Dësch | table |
| Markt | Maart | market |
| Garten | Gaart | garden |
| arbeiten | schaffen | to work |
| sprechen | schwätzen | to speak |
| kaufen | kafen | to buy |
| jetzt | elo | now |
Food is where this catches the most German speakers, because the German names sit right on the tongue. If the examiner asks about a Luxembourgish dish, the natural answer is Judd mat Gaardebounen (smoked ham with broad beans). Reach for the German dicke Bohnen and you have just told the examiner where you learned the language. Name the real Luxembourgish thing, especially food, and you sound like you live here. The full swap list lives in German words in Luxembourgish.
A spelling habit travels with this. Luxembourgish does not patch its vowels with German-style oe, ae, or ue. It is schéin (beautiful), not schön. The accents are not decoration. They change the word.
The rule German speakers get wrong most
Luxembourgish drops a final n in most situations, and German does not. Native speakers do it without thinking, in speech and in writing. Get it even roughly right and you jump from "textbook" to "real."
Drop a final n, unless the next word starts with a vowel or with one of d, h, n, t, z.
So den Mann becomes de Mann (the man) and den Bus becomes de Bus (the bus), because m and b are not on the keep list. But den Apel (the apple) keeps its n before a vowel, and den Dësch (the table), den Hond (the dog), den Tiger (the tiger), and den Zuch (the train) all keep it before d, h, t, z. Verbs work the same way. Ech kommen elo (I am coming now) keeps the n before a vowel, while Ech komme muer (I am coming tomorrow) drops it before m. Watch the one that surprises German speakers: b does not protect the n.
A German ear wants to say every n. That is the tell. You do not need to track it mid-sentence in the exam. Train it on the few sentences you will actually use, until it runs on its own. We walk through the whole pattern, including where it does not apply, in the Eifeler Regel. For a German speaker, this is the highest-value hour of practice you can spend.
What to practice, and what to ignore
You can safely set aside most of what a German speaker worries about. Your accent is close. Your sentence structure is closer still. Spend your time where it actually moves your score.
| Worth your time | Skip it |
|---|---|
| The eight word swaps above, said aloud | Memorising long answers |
| The n-rule on your own stock sentences | Rare n-rule exceptions |
| Naming Luxembourgish food and places | Worrying your German accent disqualifies you |
A good stock sentence to drill first: Ech wunnen zu Lëtzebuerg an ech schaffen zu Kirchberg (I live in Luxembourg and I work in Kirchberg). It carries the n-rule, the verb schaffen, and the joining word an, all in one breath. Another, for the everyday-routine question: Moies iessen ech Brout mat Kéis an drénke Kaffi (in the morning I eat bread with cheese and drink coffee), a plain sentence with no German hiding in it.
The exam itself is shorter than the worry around it. Speaking is 10 minutes, the interview first and then a picture to describe, both at level A2. Listening is 35 minutes at B1, a level above your speaking. You pass with at least 50 percent in speaking, or with a speaking-and-listening average of at least 50 percent, rounded up, if speaking falls short. The fee is 75 euros.
| Part | Length | Level |
|---|---|---|
| Speaking, interview then picture | 10 minutes | A2 |
| Listening | 35 minutes | B1 |

That A2 speaking bar is everyday talk, and your German carries you most of the way to it. Pick one everyday sentence today, swap any German word inside it for its Luxembourgish form, and say it out loud five times until the German version stops coming first.
