TLDR
Luxembourg has three official languages: Luxembourgish, French and German. Luxembourgish is the national language, French is the language of the law, and German dominates the press and early schooling. English is not official but works in business, hotels and most restaurants in the capital. Portuguese is the most common immigrant language. Most residents switch between three or four languages in a single day.

The short answer
The languages spoken in Luxembourg are Luxembourgish, French and German, all three recognized by the 1984 language law. Luxembourgish is the national language, the one people speak at home and with friends. French and German handle administration, the courts and the written word. English fills the gaps, especially in finance and international companies.
The practical result is a country where almost everyone is multilingual by default. According to the Luxembourg government’s language overview, the 2018 Ministry figures put French at 98% of the population, English at 80%, German at 78% and Luxembourgish at 77%. Those are self-reported abilities, so treat them as a rough guide. They still show the main point: more people in Luxembourg speak French than speak Luxembourgish.
What each language does
| Language | Official status | Where you’ll meet it |
|---|---|---|
| Luxembourgish | National language, administrative language | Home, friends, parliament debates, local radio, spoken service |
| French | Administrative language, language of legislation | Laws, court documents, restaurant menus, street signs, shops |
| German | Administrative language | Newspapers, primary school literacy, some official forms |
| English | Not official | Finance, EU institutions, tech, hotels, tourist areas |
| Portuguese | Not official | Construction, cleaning, hospitality, family life for the largest foreign community |
Languages in daily life
Luxembourgish is a Germanic language, closely related to the Moselle Franconian dialects across the border in Germany. A German speaker can follow some of it, but not all. It is the language of the Chamber of Deputies’ debates and of the dinner table. Ask for a coffee in a village café and the reply often comes in Luxembourgish before the server reads you as a foreigner.
French runs the written side of the state. Laws are published in French. Official letters to you usually arrive in French, and menus in the capital lean French too. A pharmacist, a cashier or a bank clerk will default to it with strangers.
German is what people read. Luxemburger Wort, the biggest daily newspaper, is mainly in German, and much news and television content comes in German too. Many Luxembourgers read German fluently and rarely say so.
English has no legal standing and plenty of practical weight. International firms and EU bodies operate in it, and a large share of the workforce uses it as the common denominator, since a Portuguese cleaner, a French banker and a German lawyer rarely share another language.
How Luxembourg got here
For most of its history Luxembourg sat between France and Germany and took on both. The spoken dialect was Germanic. The language of administration, after centuries of French and Austrian rule and then a 19th-century independence under a dynasty that favored French, was French and German.
Luxembourgish had no standard spelling for a long time. An official orthography came in 1946 and was reformed in 1975 and again in 1999, which is why older Luxembourgish texts look different from today’s. The 1984 language law is the key moment: it named Luxembourgish the national language, confirmed French as the language of legislation, and allowed French, German and Luxembourgish in administrative and judicial matters. In practice, an official is expected to answer you in the language you wrote or spoke in, if they can.
Why schools switch languages
Schooling explains much of the multilingualism. Children start with Luxembourgish in early years education. Literacy in primary school is taught in German, and French is introduced in the second year of primary. Further up, secondary schools in the traditional track keep German for the lower grades and switch to French for most subjects later on. English arrives as a subject in secondary school.
A child who grows up in Luxembourg therefore passes through three languages before 18, with English added on top. It is demanding, and it is a frequent source of difficulty for children of newly arrived families who speak none of the three at home. It also explains why locals tend to be patient with language learners: nearly everyone has been one.
Immigrant languages
Foreign residents make up roughly 47% of the population, one of the highest shares in Europe, and that changes what you hear on the street. Luxembourg’s foreign population, the largest communities by nationality and ethnicity, shapes everyday speech in neighborhoods and workplaces. STATEC, Luxembourg’s national statistics office, publishes the census and population data if you want the current numbers by nationality and home language.
Portuguese is the clearest example. Portuguese nationals are the largest foreign community, and Portuguese is spoken in shops, bakeries, building sites and many homes. In some towns, you can live a full day in Portuguese without trouble. Italian has a long history in the south, tied to the steelworks that drew workers a century ago. Newer communities speak French, Belgian French, German, English, and a growing list of others.
Which language to use: visitor, worker, new resident
As a visitor. Start in English or French. Hotels, restaurants and attractions in Luxembourg City handle English without effort. A “bonjour” opens most doors. A “moien” (hello in Luxembourgish) gets a smile and often a more relaxed conversation. You don’t need any of the three to get around.
As a worker. Check the job ad. Finance and international firms work in English or French. Local retail, healthcare, the public sector and trades often want French plus Luxembourgish or German. Do you need French to work in Luxembourg? For most jobs outside a few English-only workplaces, yes, or at least a working level.
As a new resident. Learn French first for paperwork and daily errands, then add Luxembourgish if you plan to stay. Citizenship requires a Luxembourgish language test, and the government subsidizes courses through the National Institute for Languages. German helps with newspapers, TV and the school system. English alone will get you through the first months but gets thinner when you deal with the commune, a landlord or a doctor.
The takeaway
Luxembourg’s languages are not a hierarchy. They are a toolkit, each one used where it fits. Speak English and you will be understood almost anywhere in the capital. Add French and you can handle nearly everything. Add Luxembourgish and you cross from visitor to local.
