The nickname "The Windy City" is synonymous with Chicago. Instead of using this term repeatedly, there are plenty of other phrases or words you can use to describe the city. For instance, Chi-Town is a slang term for Chicago. The Second City is also a popular nickname given that it was once the second-largest city in the USA (it has since been eclipsed by Los Angeles). Other nicknames include the City of Big Shoulders (coined by poet Carl Sandburg), and the City that Works (referring to Chicago's industrial past). Additionally, there's the nickname "Hog Butcher to the World" as suggested by Carl Sandburg in his poem, noting Chicago's past reputation as a hub for the meatpacking industry.
