What language is spoken in Brussels?

Brussels runs on French in daily life, despite a constitutional compromise that makes the Brussels-Capital Region officially bilingual in French and Dutch. Every STIB/MIVB metro announcement, every government form, and every street sign appears in both languages. In practice, over 85% of the region's 1.2 million residents across 19 communes speak French at home, according to recent Taalbarometer surveys. You'll hear Dutch in government offices and occasionally in the northern commune of Neder-Over-Heembeek, but the waiter at Chez Léon near Grand-Place, the barista pulling shots in Saint-Gilles, and the ticket seller at the Atomium will all default to French. Order "un café" at any spot along Rue Dansaert and nobody blinks. Ask for "een koffie" in Dutch and you might get a puzzled look before they switch to French anyway.

English works well in Brussels. Belgium consistently ranks in the top 10 on the EF English Proficiency Index, and Brussels skews higher than the national average because roughly 50,000 EU and NATO staff live in the Quartier Européen around Schuman station. In the tourist core between Grand-Place, the Sablon antiques quarter, and the Marolles flea market, most people under 50 can hold a full English conversation. That comfort level drops noticeably among older stallholders at the Sunday morning Jeu de Balle market and at neighborhood friteries outside the center. The clatter of metal scoops at a Marolles friture tends to drown out any language anyway. One context where English reliably fails is Belgian bureaucracy. If you need to file a police report at the Palais de Justice or deal with a commune office, bring Google Translate or a French-speaking friend.

You need maybe 4 French phrases to shift how Brussels treats you. "Bonjour" when entering any Brussels shop is non-negotiable. Walk into a bakery on Rue du Bailli in Ixelles without saying it and the temperature drops about 10 degrees. "S'il vous plaît" tacked onto any request softens the whole transaction. "L'addition" gets the bill at a restaurant. Belgian waiters will never bring it unprompted, which can leave you sitting at a Sainte-Catherine seafood spot for 20 minutes after the moules-frites have gone cold and the last Leffe is warm in the glass. The Dutch "dank u" for thank you tends to charm people more than the French "merci" because it signals awareness that Brussels sits on Belgium's language border. That said, don't attempt Brusseleer, the old local dialect that folds French and Dutch together. A small number of older Marolliens still speak it. If you attempt it as a tourist, it reads as mockery rather than effort.

Brussels uses the Latin alphabet with a few French accents (é, è, ç) and Dutch letter pairs (ij, ui, oe) that any English reader can parse. Brussels place names follow no single pronunciation logic. "Schuman" is "SHOO-mahn," not the German way. "Ixelles" is "eek-SELL." "Uccle" is "OOK-luh." The Flemish names for the same communes, Elsene and Ukkel, appear on signs but almost nobody uses them in conversation. At STIB metro stations like De Brouckère and Porte de Namur, the recorded announcements echo between French and Dutch before each stop, and the ticket machines default to French but have an English toggle in the top-right corner. Tap it before fumbling with 2-euro coins at the counter. Google Translate's camera mode handles French-only restaurant menus well, though most places within 500 meters of Grand-Place print English menus without being asked.
