Language learning for adults

Multilingualism is ubiquitous in Luxembourg, whether in everyday life or at work. No matter the situation, you should expect to speak a different language or be addressed in a language other than your native tongue.

To integrate as well as possible in Luxembourg, it is important to speak several languages. And proficiency in foreign languages is a genuine policy priority aimed at integrating newcomers as quickly as possible. People interested in learning new languages have every opportunity to do so.

A wide range of language learning providers in Luxembourg

The range of language courses available in Luxembourg is very extensive, whether through public integration agencies or private institutions.

The INLL, a key player in language learning

The National Institute of Languages of Luxembourg (INLL) is a key player in language learning in Luxembourg. For a very modest annual fee, you can learn up to 8 languages, including Luxembourgish , German, French, Chinese, Italian, Spanish, and Portuguese, with certifications included. There’s no excuse not to integrate into Luxembourg’s diverse communities!

Nearly 17,000 registrations were recorded for the 2024–2025 academic year, with a notable increase in national and international certifications (+9.5%).

The INLL is notably the provider selected by the Employment Development Agency (ADEM) to help job seekers boost their employability through intensive professional language courses (Luxembourgish, German, English, French).

Places at the INLL are in high demand. Be sure to register well in advance. Sessions run on a semester basis.

French remains the most popular language, followed by Luxembourgish.

Private providers for language learning in Luxembourg

You will also find many private companies in Luxembourg offering language courses on an individual basis, either inter-company or intra-company.

These companies, which specialize in language learning, also typically organize intensive language camps for children during school breaks in French, German, or English.

Although more expensive than the INLL, this option allows you to learn a language more quickly through intensive courses.

Learning Luxembourgish

Learning Luxembourgish is an important step toward local integration.

Luxembourgish is one of the three official languages in Luxembourg. Proficiency in the language is essential for obtaining Luxembourgish citizenship, as this requires passing a written and oral Luxembourgish test.

Here are some basic Luxembourgish phrases to help you integrate more easily.

Training leave to learn Luxembourgish

Do you work in Luxembourg and want to learn Luxembourgish? As an employee, self-employed individual, or independent professional, you are eligible for specific paid leave to learn Luxembourgish or improve your proficiency in the language.
This special leave can amount to up to 200 hours over the course of your professional career.

Learn Luxembourgish through public institutions

With the aim of integrating their residents, many municipalities in Luxembourg offer Luxembourgish language courses to their residents. Check directly with your municipality of residence.

The City of Luxembourg, for example, offers courses in the Luxembourgish language and culture for adults. These courses are divided into four levels: beginner, intermediate, advanced, and oral proficiency. Classes are held from September through July, twice a week. You can find detailed course content and schedules on the VDL website.

In addition, language courses as part of academic support are directly administered in Luxembourg schools for new expatriate students to facilitate their integration.

Public integration organizations such as ASTI or CLAE also offer courses in Luxembourgish and other official languages to help newcomers integrate into Luxembourg.

Learning Luxembourgish online

There are also many ways to learn Luxembourgish.
