Capital or Capitol: What Is the Difference?

The difference between capital and capitol is meaning. These words are homophones, which means they are pronounced the same way but spelled differently and used for different things.

Capital is the more common word. It can refer to a city, money, importance, assets, or uppercase letters. If you are not talking about a government building, capital is probably the word you need.

Capitol is much narrower. It refers to a building where a legislative body meets. In the United States, the Capitol with a capital C often refers specifically to the United States Capitol building in Washington, D.C.

Word	Meaning	Example
Capital	A city, money, uppercase letter, or something important	The capital of Japan is Tokyo.
Capitol	A government building where lawmakers meet	The senator walked into the capitol.

If the word means a place where government happens as a city, use capital. If it means the actual building, use capitol.

What Does Capital Mean?

Capital has several meanings, which is why it appears much more often than capitol. The most common meaning is a city that serves as the center of government for a country, state, or region.

Examples:

• Madrid is the capital of Spain.
• Austin is the capital of Texas.
• The capital city has many government offices.

In these examples, capital means the city where the government is based. It does not mean one building. That is an important distinction. A city can be a capital, but a building is a capitol.

Capital can also mean money or financial resources used to create, run, or expand something.

• The company raised enough capital to open a second location.
• You need capital before launching the project.
• Investors provided the capital for the new business.

In grammar, capital can refer to uppercase letters.

• Use a capital letter at the beginning of a sentence.
• Your name should start with a capital letter.
• The sign was written in capital letters.

Capital can also describe something serious, major, or extremely important.

• That was a capital mistake.
• Clean water is of capital importance.
• The judge discussed a capital offense.

Because capital has so many meanings, it is the correct spelling in most sentences.

What Does Capitol Mean?

Capitol refers to a building where lawmakers meet. It is most often used in government contexts. A state capitol is the building where the state legislature meets. The United States Capitol is the building where Congress meets.

Examples:

• The capitol building has a large dome.
• Protesters gathered outside the state capitol.
• The governor gave a speech at the capitol.
• Visitors toured the Capitol during their trip to Washington, D.C.

Notice that capitol refers to the building, not the city. This is the key difference. Washington, D.C., is the capital of the United States. The Capitol is the building where Congress meets.

That means these two sentences are both correct, but they use different words for different reasons:

• Washington, D.C., is the capital of the United States.
• The United States Capitol is in Washington, D.C.

The first sentence talks about the city. The second sentence talks about the building.

When to Use Capital

Use capital when you are talking about a city that serves as a center of government.

• Ottawa is the capital of Canada.
• The capital city is busy during election season.
• They moved to the state capital for work.

Use capital when you are talking about money, assets, or business resources.

• The startup needs more capital.
• They invested their capital wisely.
• The project failed because it lacked capital.

Use capital when you are talking about uppercase letters.

• Write the title with capital letters.
• The word should begin with a capital.
• Do not use all capital letters unless you need emphasis.

Use capital when something is major, serious, or important.

• This is a matter of capital importance.
• The company made a capital investment.
• The law deals with capital punishment.

In short, if your meaning is not specifically a legislative building, capital is usually correct.

When to Use Capitol

Use capitol only when you are talking about a building connected to lawmakers or a legislature.

• The bill was debated at the capitol.
• Students visited the state capitol on a field trip.
• The capitol was crowded during the hearing.
• The Capitol is one of the most recognizable buildings in Washington, D.C.

The word capitol is more limited than capital. It does not mean a city, money, importance, or uppercase letters. It points to a physical government building.

You may also see Capitol Hill. In the United States, this phrase can refer to the area around the U.S. Capitol or, more broadly, to Congress and federal lawmaking.

• The reporter covers news from Capitol Hill.
• The debate on Capitol Hill lasted all week.

In these examples, Capitol is capitalized because it is part of a specific place name.

Capital City or Capitol City?

The correct phrase is capital city, not capitol city. A city that serves as the seat of government is a capital. The building where lawmakers meet is a capitol.

Correct:

• Rome is the capital city of Italy.
• The capital city attracts many visitors.
• The state capital city is home to several government offices.

Incorrect:

• Rome is the capitol city of Italy.
• The capitol city attracts many visitors.
• The state capitol city is home to several government offices.

Use capital city when you mean the city. Use capitol building when you mean the building.

Capital Building or Capitol Building?

The correct phrase is usually capitol building if you mean the building where lawmakers meet.

Correct:

• The capitol building is open to the public.
• The state capitol building has a beautiful dome.
• They walked up the steps of the capitol building.

However, if you are using capital in a different sense, such as an important building or a building in the capital city, then the sentence may need to be rewritten for clarity.

For example, “capital building” can sound confusing because readers may wonder whether you mean an important building, a financial building, or a building in the capital. If you mean the government building, write capitol building.

Common Mistakes With Capital and Capitol

The most common mistake is using capitol when you mean the city where a government is based.

Incorrect:

• Albany is the capitol of New York.
• London is the capitol of England.
• What is the capitol of Australia?

Correct:

• Albany is the capital of New York.
• London is the capital of England.
• What is the capital of Australia?

Another mistake is using capital when you mean the government building.

Incorrect:

• The senator entered the capital.
• The hearing took place inside the state capital.
• The crowd gathered near the capital building.

Correct:

• The senator entered the capitol.
• The hearing took place inside the state capitol.
• The crowd gathered near the capitol building.

The easiest way to avoid the mistake is to ask one question: Am I talking about a city or a building? City equals capital. Building equals capitol.

• Capitol has an o.
• A capitol is often a government building with a round dome.

You can also remember this line:

The capital is the city. The capitol is the building.

That sentence covers the most common confusion. If you mean the seat of government as a city, choose capital. If you mean the building where lawmakers meet, choose capitol.

Final Answer

Capital and capitol are both correct words, but they are used differently. Use capital for a city, money, uppercase letters, resources, or something important. Use capitol for a government building where lawmakers meet.

The easiest rule is simple: capital is the word you need most of the time. Capitol is only for the building.
