Capitol and capital are both correct words, but they do not mean the same thing. The difference is mainly about government buildings, cities, money, and importance.
Use capitol when you mean a building where a government legislature meets, especially the U.S. Capitol. Use capital for a city that serves as the seat of government, money or wealth, an uppercase letter, or something very important.
Because the two words sound almost identical, they are easy to mix up. In this guide, you will learn their meanings, correct usage, common mistakes, and a simple way to remember the difference.

What Does Capitol Mean?
Capitol means a building where a legislative body meets. The word is most strongly associated with the United States, where the U.S. Capitol is the building in Washington, D.C., where the U.S. Congress meets.
