Illinois is a state that spans the bright lights and skyscrapers of Chicago to the quiet farmland and small towns down south. Known as the Prairie State, it’s anchored by a rich history of industry, innovation, and the diverse cultures that call it home. Whether you’re exploring Navy Pier or roaming the cornfields, here are 18 slang terms to help you sound like a true Illinoisan.
The Prairie State
Illinois’s official nickname, paying homage to the vast prairies that once covered much of its landscape. You’ll see references in everything from tourism brochures to local restaurant menus.
Chi-Town
A shorthand for Chicago, particularly in casual conversation. Don’t be surprised if you hear “Chi-Town pride” shouted from a sports bar whenever the Bears, Bulls, or Blackhawks clinch a win.
The Windy City
Another name for Chicago, thanks to its famous Lake Michigan breezes (and some say, long-winded politicians). Locals toss “the Windy City” around as a badge of honor—just bring a jacket if you’re visiting in winter.
Da Bears
The rallying cry for Chicago Bears football fans—drawn out in a thick, sometimes exaggerated Chicago accent. If you hear “Da Bears!” loud and clear, you’re either at Soldier Field or around some serious super fans.
Deep Dish
Not just pizza—this is Chicago pizza, thick and loaded with sauce on top. If someone says “I’m grabbing some deep dish,” they’re about to enjoy a cheesy, sauce-filled slice of local tradition.
The L
Chicago’s elevated train system that snakes above (and occasionally below) the city streets. Hop on “the L” to get from Wrigleyville to the Loop without battling downtown traffic.
The Loop
The bustling business district in downtown Chicago, bordered by the elevated tracks. If someone says “I work in the Loop,” they’re navigating skyscrapers, corporate life, and that ever-present city buzz.
312
One of Chicago’s most iconic area codes. You’ll see 312 on T-shirts, hats, even craft beer—always a nod to the city’s central heart.
Gym Shoes
What most of the country calls “sneakers” or “tennis shoes,” Chicagoans often refer to as “gym shoes.” So, if someone says “Nice gym shoes!” they’re complimenting your kicks.
Jewel
The local way of referring to Jewel-Osco, a major grocery chain in Illinois. “I’m running to the Jewel” means you’re making a quick grocery run, likely grabbing some pop and snacks for a Bears game.
Pop
The Midwestern term for “soda.” Don’t ask for a “Coke” unless you specifically want a Coca-Cola—around here, it’s “pop,” plain and simple.
Lake Effect
Refers to the weather phenomenon where Lake Michigan ramps up snowfall or storms. When you hear “lake effect,” brace yourself—winter’s about to show its teeth.
The Collar Counties
The suburban counties surrounding Chicago—DuPage, Kane, Lake, McHenry, and Will. If someone says they live in “the collar,” they’re likely commuting into the city or enjoying suburban life just outside it.
Horseshoe
Not just a U-shaped piece of metal for a horse’s hoof—it’s a dish hailing from Springfield. A Horseshoe is an open-faced sandwich of meat (often hamburger), topped with fries and smothered in cheese sauce—comfort food at its finest.
The Expressways
Refers to Chicago’s highways, often identified by names rather than numbers (the Dan Ryan, the Eisenhower, the Kennedy). If someone says, “I’m stuck on the Ryan,” they’re likely sitting in traffic on I-90/94.
The Magnificent Mile
A stretch of North Michigan Avenue in downtown Chicago, lined with upscale shops, restaurants, and landmarks. Locals might shorten it to “Mag Mile” and treat it as the city’s prime shopping destination.
Portillo’s
A beloved Chicago-based chain known for hot dogs, Italian beef, and chocolate cake shakes. If someone says they’re “craving Portillo’s,” they’re about to indulge in a true Illinois feast.
Tavern-Style Pizza
The crispy, thin-crust alternative to deep dish—cut into squares. Mention “tavern-style” to locals, and you’ll spark a debate over which style truly reigns in the city.
These slang terms and references bring you inside the cultural currents that flow through both Chicago and the rest of the Prairie State. Whether you’re navigating the city on “the L” or tasting your first Horseshoe in Springfield, you’ll find that Illinois offers a diverse slice of Americana. Pick up the lingo, embrace the local pride, and you’ll feel right at home saying “Da Bears!” in no time.
