Have you ever seen a word wearing a "fancy hat"? A capital letter is like that fancy hat. It helps show that a word is a special name. When writers use capitals in the right places, readers can quickly tell the difference between an ordinary word and the name of a holiday, a product, or a place. That makes writing clearer and easier to read.
We use a capital letter at the beginning of a sentence, but we also use capitals for special names. These special names are called proper nouns. A proper noun names one special person, place, thing, or event. A common noun names any person, place, thing, or event.
For example, city is a common noun. It could mean any city. But Denver is a special city name, so it is a proper noun and needs a capital letter. The same idea helps us with holidays, product names, and geographic names.
Capitalization means using uppercase letters in the correct places.
Proper noun means the special name of a person, place, thing, or event.
Common noun means a general word for a person, place, thing, or event.
When you write, ask yourself, "Is this just any thing, or is it the special name of one thing?" If it is a special name, it probably needs a capital letter.
The first kind of special name in this lesson is a holiday. A holiday name is the special name of a celebration or special day. Holiday names always begin with capital letters.
Here are some examples: Halloween, Thanksgiving, New Year's Day, Memorial Day, Labor Day, Valentine's Day, and Independence Day.
If the holiday has more than one word, capitalize the important words in the name. That is why we write New Year's Day and Martin Luther King Jr. Day with capitals.
Read these examples carefully:
I wore a costume on Halloween.
We eat a big meal on Thanksgiving.
School is closed on Memorial Day.
We watched fireworks on Independence Day.
Holiday names are special event names. Even if a holiday happens every year, its name is still treated like a special title. That is why each important word in the holiday name begins with a capital letter.
Be careful with apostrophes too. In New Year's Day and Valentine's Day, the capital letters still stay because the whole phrase is a holiday name.
Some time words do not need capitals unless they are part of a holiday name. Words like day, month, year, winter, and summer are usually common nouns.
Look at the difference:
We went to the park on a sunny day.
We went to the parade on Labor Day.
Many animals rest in winter.
We visit family on New Year's Day.
In the first sentence, day is just a common word, so it stays lowercase. In the second sentence, Labor Day is the special name of a holiday, so both words are capitalized.
Some holidays include words that are usually lowercase, but those words become capitalized when they are part of the holiday's special name.
Another thing to remember is that ordinary celebrations are not always holiday names. If you say birthday party, those words are usually lowercase because they are not the official name of a holiday. But if you say Mother's Day, that is a holiday name and should be capitalized.
The next kind of special name is a product name. A product name is the special brand name of something people make or sell. Product names use capital letters because they are proper nouns.
Think about things you may see at home or school. Crayola crayons, Lego bricks, Nike shoes, Apple's iPad, and Nintendo Switch are all product names. They need capitals because they name specific brands or products.
Examples:
I colored the picture with Crayola crayons.
My brother built a tower with Lego blocks.
She played a game on her Nintendo Switch.
Dad wore his Nike sneakers.
Sometimes a product name has more than one word. Then each important part of the name is capitalized, such as Play-Doh or Hot Wheels.
Looking at a product name in a sentence
Sentence: We ate Oreo cookies after lunch.
Step 1: Find the special name.
The special brand name is Oreo.
Step 2: Decide if it names a specific product.
Oreo is a brand, so it is a product name.
Step 3: Capitalize it correctly.
Write Oreo, not oreo.
The corrected sentence is: We ate Oreo cookies after lunch.
Writers sometimes see product names on boxes, signs, and screens. Those names usually help show the correct capitalization. When you copy the name in your own writing, keep the capitals.
This is an important difference: a common noun names a general item, but a product name names a specific brand. For example, shoes is a common noun. Nike is a product name. tablet is a common noun. iPad is a product name.
| Common noun | Product name |
|---|---|
| crayons | Crayola crayons |
| blocks | Lego bricks |
| cookies | Oreo cookies |
| tablet | iPad |
| shoes | Nike shoes |
Table 1. This table compares general item names with specific product names.
If you write, "I need crayons," the word crayons does not need a capital because it is general. If you write, "I need Crayola crayons," the brand name Crayola does need a capital.
Remember that not every word in a sentence needs a capital letter. Use capitals only when the word has a special job, such as naming a holiday, a brand, or a place.
Some product names use unusual capital letters, such as iPad. When a company gives a product a special way of writing its name, writers try to copy that spelling carefully.
The last big group in this lesson is geographic names. A geographic name is the special name of a place on Earth. These names always begin with capital letters.
Geographic names include continents, countries, states, cities, streets, parks, rivers, mountains, deserts, and oceans.
Examples of geographic names are North America, United States, Colorado, Denver, Main Street, Yellowstone National Park, Mississippi River, Rocky Mountains, and Pacific Ocean.
Read these sentences:
My aunt lives in Texas.
We visited the Grand Canyon.
The fish swam in the Atlantic Ocean.
Our class read a map of Africa.
The bear lived near the Rocky Mountains.
Geographic names are official place names. A place may be very large, like a continent, or smaller, like a street or park. If it is the special name of the place, it gets a capital letter.
Words that are part of the place name are capitalized too. That is why we write Lake Michigan, Elm Street, and Mount Everest. The words Lake, Street, and Mount are part of the official names.
Sometimes direction words can be tricky. Words like north, south, east, and west are not always capitalized.
If the word tells a simple direction, it stays lowercase. Example: We drove north for two hours.
If the word is part of a special place name, it gets a capital letter. Example: We live in North America.
Look at these pairs:
The geese flew south in winter.
My cousin moved to South Dakota.
The sun rises in the east.
They traveled across the East River.
In each pair, the lowercase word is just a direction. The capitalized words are part of a special geographic name.
Checking a place name
Sentence: we swam in the pacific ocean.
Step 1: Find the place name.
The special place is Pacific Ocean.
Step 2: Decide if it is an official geographic name.
It names one specific ocean, so it is a geographic name.
Step 3: Fix the capitals.
Capitalize Pacific and Ocean.
The corrected sentence is: We swam in the Pacific Ocean.
You can use this same thinking with city names, street names, and landforms. Ask: "Is this the special name of a place?" If the answer is yes, use capital letters.
Good writers check capitalization when they revise and edit. Reading your sentence slowly can help. Look for holiday names, product names, and geographic names. Then make sure each special name begins with a capital letter.
Compare these incorrect and correct examples:
Incorrect: we went to yellowstone national park on memorial day.
Correct: We went to Yellowstone National Park on Memorial Day.
Incorrect: my sister got a lego set for christmas.
Correct: My sister got a Lego set for Christmas.
Incorrect: uncle ray drove across the united states in his ford truck.
Correct: Uncle Ray drove across the United States in his Ford truck.
Editing a sentence with different kinds of names
Sentence: on thanksgiving we drove to new york in our toyota car.
Step 1: Find the holiday name.
Thanksgiving is a holiday, so it needs a capital letter.
Step 2: Find the geographic name.
New York is a place name, so both words need capitals.
Step 3: Find the product name.
Toyota is a car brand, so it needs a capital letter.
Step 4: Check the beginning of the sentence.
The first word, On, also begins with a capital letter because it starts the sentence.
The corrected sentence is: On Thanksgiving we drove to New York in our Toyota car.
One sentence can have more than one kind of special name. That is why careful editing matters. A holiday name, a product name, and a place name may all appear together.
As you grow as a writer, capitalization becomes part of showing respect for names. We capitalize special holidays, special products, and special places because their names matter. Those capital letters help readers understand exactly what you mean.
