Capital vs. Capitol

1 min read

Capital and capitol sound identical, but their meanings are very different. One is used in many contexts, while the other is used in only one very specific situation.

Capital

Capital has several common meanings:

The main city of a country or region: Paris is the capital of France.
Money or assets used for investment: The company raised more capital.
Uppercase letters: Please write your name in capital letters.
Excellent or important (older usage): That’s a capital idea!

Capitol

Capitol refers only to a specific type of building:

The building where a government’s legislature meets.
Most famously, the U.S. Capitol in Washington, D.C.

In the United States, “Capitol” is capitalized when referring to the actual U.S. Capitol building.

💡 Tip

Capitol → building has a dome (think of the “o”).
Capital → everything else (city, money, letters).
