Why learn Luxembourgish?
It’s the language of nationality, work and belonging in Luxembourg — and almost nobody teaches it well.
Nationality & the Sproochentest
Luxembourgish is required for naturalisation. Daily vocabulary practice is the foundation the Sproochentest and INL courses build on.
Work & everyday life
From the commune to the crèche, Lëtzebuergesch opens doors CVs can’t. Understanding colleagues and neighbours changes everything.
Resources are scarce
The big language apps don’t offer Luxembourgish at all. 16Word gives it the same first-class treatment as French or German.
An official certificate, not just an app badge
Reach a CEFR vocabulary level and claim a certificate with your name, a unique serial, and a QR code anyone can scan to verify it — retention-proven after 90 days.
Sample shown. Every real certificate has its own serial number and public verification page.
Built for Lëtzebuergesch, not adapted to it
Most Luxembourgish audio online is text-to-speech. Ours isn’t.
Real human voices
2,500+ words pronounced by native speakers, re-hosted from the Lëtzebuerger Online Dictionnaire (lod.lu, CC0) — not a robot voice.
Real IPA & accepted synonyms
Phonetic transcriptions and accepted alternative answers come from LOD too — write d’Haus or Haus, both count.
The 16-word game loop
Active recall locks words in; clean answers bank Tetris pieces and every 6 words you play a quick brain-break. 5 minutes a day.
Learn offline
Download your categories and keep practising on the train, the plane, or anywhere the Wi-Fi isn’t.
