What Does Capital Mean?

Capital has several meanings in English. It can function as both a noun and an adjective. Its meaning depends on the sentence and context. Here are its most common uses.

Capital as a City or Seat of Government

A capital is a city where a country’s or state’s government operates. It serves as the official center of government. For example:

• Washington, D.C., is the capital of the United States.
• Austin is the capital of Texas.
• Denver is the capital of Colorado.
• Sacramento is the capital of California.

The term capital city refers to this type of city. You can also use national capital for a country’s main seat of government.

Capital as Money, Wealth, or Assets

Capital can also mean money, wealth, or resources available for business and investment. Individuals and companies use capital to support their financial activities. It may include cash, property, equipment, and other resources. Here are some common financial expressions:

• Financial capital: money and financial resources available for use
• Venture capital: money invested in businesses with growth potential
• Working capital: funds available for a company’s daily operations
• Human capital: people’s skills, knowledge, and abilities
• Political capital: influence or public support that someone can use
• Social capital: value gained through relationships and social networks
• Capital gains: profits from selling an asset for more than its cost
• Capital assets: valuable property or resources owned by a person or business

Example: The company needs additional capital to expand its operations. In this sentence, capital means money or financial resources. It has nothing to do with a government building.

Capital as an Uppercase Letter

A capital is also an uppercase letter of the alphabet. These letters have a different form from lowercase letters. For example:

• A is a capital letter, while a is lowercase.
• B is a capital letter, while b is lowercase.
• C is a capital letter, while c is lowercase.

Writers use capital letters at the beginning of sentences and in proper names. Example: Always write the name Sarah with a capital S. The correct expression is capital letter, never capitol letter.

Capital as an Adjective

Capital also works as an adjective. It can describe something important, serious, excellent, or related to money. Here are its main adjective meanings:

• Chief or principal: Capital can describe something that ranks first in importance. Example: Her capital concern was the safety of her children.
• Most serious or punishable by death: In legal language, capital describes crimes or punishment involving the death penalty. Examples: capital offense, capital crime, capital punishment.
• Excellent or first-rate: Capital can mean excellent or very good. This usage is old-fashioned and less common today. Example: We had a capital time at the fair.
• Related to financial resources: Capital can describe investments or other financial matters. Example: The business received capital investment from several partners.

Notice that all these expressions use capital with an A. None uses capitol.

Capital as a Preeminent City

A city can also be called a capital because it leads a particular field, industry, or activity. This meaning does not require the city to be a seat of government. For example:

• Paris is known as a fashion capital.
• Los Angeles is often described as a movie capital.
• New York City is a major financial capital.

These expressions describe a city’s influence or importance in a particular area. For instance, Albany is New York’s official state capital. New York City, however, is a major financial center. This distinction shows why capital has a much broader meaning than capitol.

What Does Capitol Mean?

A capitol is a building where a legislative body meets. Legislators use this building to debate, discuss, and pass laws. In the United States, the word usually refers to the federal Capitol in Washington, D.C., or a state legislative building. Unlike capital, capitol does not refer to money, an uppercase letter, or a government city.

What Is the U.S. Capitol?

The United States Capitol is the building where the U.S. Congress meets. It stands in Washington, D.C., and serves as the seat of the legislative branch. The building contains two main legislative chambers:

• Senate: where U.S. senators meet and conduct legislative business.
• House of Representatives: where members of the House meet to debate and vote on legislation.

The Capitol is also known for its large dome and the Statue of Freedom above it. Example: Visitors tour the U.S. Capitol each year. Here, Capitol refers to one specific federal building, not the entire city.

What Is a State Capitol?

A state capitol is a building where a state’s legislature meets. For example:

• The Texas State Capitol is in Austin.
• The Colorado State Capitol is in Denver.
• The California State Capitol is in Sacramento.

Notice that the city and building have different meanings in terms of spelling. Austin is the capital of Texas, while the Texas State Capitol is the building. The word statehouse is another term for a state legislative building. Example: The governor attended a public event outside the state capitol. Here, capitol refers to the building. It does not refer to the city where the building stands.

Capitol Hill vs. Capital Hill

Capitol Hill is the correct spelling when referring to the famous area in Washington, D.C. The phrase has several related meanings. It can refer to:

1. A geographic location: the hill where the U.S. Capitol stands.
2. A neighborhood: a historic residential area surrounding the Capitol.
3. A political expression: a common reference to Congress and U.S. legislative activity.

For example:

• The family lives in the Capitol Hill neighborhood.
• The senator returned to Capitol Hill after the election.
• Lawmakers held a meeting on Capitol Hill.

In these examples, Capitol Hill uses an O because it relates to the legislative building and its surrounding area. Capital Hill is not the standard spelling for these Washington, D.C., references.

Etymology: Where Do the Words Come From?

In this capital vs capitol history, although the words have different modern meanings, their histories share a connection. Both words trace back to the Latin word caput, meaning head. However, they developed through different Latin forms.

Origin of capital: Capital comes from the Latin adjective capitalis, meaning of the head. It later developed meanings related to something chief, principal, or important. The Latin word capitale also referred to wealth or property. Over time, English adopted several meanings of the word. These include a government city, financial resources, and an uppercase letter. The architectural meaning also has a Latin connection. It refers to the upper part, or head, of a column.

Origin of capitol: Capitol comes from the Latin word Capitolium. This was the name of an ancient Roman temple dedicated to Jupiter Optimus Maximus. The temple stood on Rome’s Capitoline Hill, one of the city’s traditional seven hills. The name eventually became associated with legislative buildings. In American English, capitol now commonly refers to a building where a legislature meets. The shared Latin connection helps explain why the words look similar. Their different histories explain why their modern meanings differ.

The U.S. Capitol: A Brief History

The U.S. Capitol is one of the most recognizable government buildings in the country. Its construction began in the 18th century, and the building has grown with the nation. Here are some important historical facts verified by the Architect of the Capitol and the U.S. Senate.

Year	Historical event
1793	President George Washington laid the Capitol’s cornerstone on September 18.
1800	Congress first met in the Capitol.
1807	The south wing was completed for the House of Representatives.
1814	British troops burned the Capitol during the War of 1812.
1856-1866	Workers constructed the cast-iron dome.
1863	The Statue of Freedom was installed on December 2.
1866	The dome’s interior work was completed.

The Capitol’s cornerstone was laid in 1793. President George Washington laid the building’s cornerstone on September 18, 1793. The building’s original design came from physician and architect William Thornton. His design featured a central structure with two wings.

Congress first met in the Capitol in 1800. At that time, the building remained unfinished. The original north wing housed the Senate. The south wing was completed in 1807 for the House of Representatives.

British troops burned the Capitol in 1814. During the War of 1812, British troops burned the Capitol in August 1814. The fire destroyed much of the building’s interior. Workers later restored and expanded the structure. These changes helped prepare it for a growing Congress.

The Capitol dome was built between 1856 and 1866. Architect Thomas U. Walter designed the Capitol’s cast-iron dome. Construction began in 1856 and finished in 1866. The project cost $1,047,291, according to the Architect of the Capitol. The dome became one of the building’s most recognizable features.

The Statue of Freedom was installed in 1863. The Statue of Freedom stands at the top of the Capitol dome. Sculptor Thomas Crawford created the original design. The bronze statue measures 19 feet and 6 inches tall. Workers installed it on December 2, 1863. It remains an important symbol of the United States Capitol.

An Easy Memory Trick

If you often confuse the words in this capital vs capitol pair, a simple memory trick can help.

• Capital means all the other meanings: think of cities, assets, alphabet letters, and important things.
• Capitol means one specific building meaning: think of the legislative building and its round dome.

Here are three ways to remember the difference:

1. A stands for all the other meanings: capital can mean a city, money, a letter, or something important.
2. O stands for only one main modern U.S. meaning: capitol refers to a legislative building.
3. The O resembles a dome: picture the round dome of the U.S. Capitol.

The most useful trick is this: a capitol building is located in a capital city. For example, the U.S. Capitol is located in Washington, D.C., the nation’s capital.

Common Capital vs Capitol Mistakes

Even experienced writers sometimes confuse the words in this capital vs capitol pair. Their identical pronunciation makes spelling mistakes easy. Here are common mistakes and their corrections.

Capital in Architecture

There is one more meaning of capital worth knowing. In architecture, a capital is the uppermost part of a column or pillar. It connects the column’s shaft to the structure above it. Architectural capitals often have decorative designs. Their shapes help distinguish different classical architectural orders. The three well-known classical types are:

• Doric capital: a simple design with a rounded cushion-like form and a square top.
• Ionic capital: recognized by its spiral scrolls, called volutes.
• Corinthian capital: known for its detailed acanthus leaf decorations.

These architectural features appear in many classical buildings. The word remains capital, with an A, because it refers to the top, or head, of a column.
