Remember that proper nouns should be capitalized, and common nouns should not be capitalized!

When to use the definite article with proper nouns in English?
In English, some proper nouns (specific names for things) are always used with the definite article the. For example:
the Empire State Building
the United States
the Panama Canal
the Beatles
But other proper nouns can never be used with a definite article:
New York
Annabelle
❌ The New York
❌ The Annabelle

What is the definite article in English and how do we use it?
The definite article in English is the word the. We use it before a or to show that you are talking about a specific noun. Let’s look at a few examples and see why we use or don’t use a definite article:
- I like books. → No definite article because this sentence is discussing any books, not a specific book.
- I didn't like the book you gave me. → We use a definite article because in this sentence we are referring to one specific book that you already know about.
- I left the books for my homework at school! → We can use a definite article in front of plural nouns, as long as they are a specific group of things that we already know about.
What is a proper noun?
A proper noun in English is a very specific name for something. For example, book is a common noun but the title of a specific book, such as Harry Potter and the Sorcerer’s Stone, is a proper noun.
Tip
Usually, a proper noun cannot be used with a definite article, even though a proper noun refers to something specific:
✅ Today I’m eating lunch with Luna.
❌ Today I’m eating lunch with the Luna.
However, there are some nouns that are always used with definite articles. Let’s have a look at some of the kinds of nouns that use the.
When do I use the definite article with a proper noun?
We use the definite article before a proper noun when the is part of the noun’s specific name. Here are some of the categories of proper nouns that often have a definite article as part of their name.
- Proper nouns with “of” in their name - the United States of America the University of Texas , the People’s Republic of China - the Republic of Korea, the Strait of Gibraltar, the Isle of Man, the Gulf of Mexico 
- Countries or groups of countries that include Republic, Kingdom, Union, Federation, Confederation, or State - the United Kingdom, the Dominican Republic, the European Union - the Russian Federation, the United Mexican States, the Swiss Confederation 
- Names for island chains - the Philippines, the Bahamas, the Hebrides - the Channel Islands, the British Isles, the Florida Keys 
- Rivers, canals, oceans, seas - the Nile River, the Panama Canal, the Indian Ocean, the Red Sea - the Thames (River), the Mississippi (River), the Erie Canal, the Amazon (River) 
- Unique geography features (e.g. deserts, forests, gulfs, peninsulas, mountain ranges,...) - the Rocky Mountains, the Andes (Mountains), the Sahara (Desert), the Balkan Peninsula, the Persian Gulf, the Black Forest - the Continental Divide, the San Andreas Fault, the 45th Parallel, the Blue Grotto, the Great Lakes, the Finger Lakes, the Great Barrier Reef - the Rocky Mountains → the Rockies - the Appalachian Mountains → the Appalachians - the Andes Mountains → the Andes 
- Proper names for groups of people (e.g. families, bands, sports teams…) - the Smiths → the Smith family- the Joneses → the Jones family- the Yankees → a baseball team- the Patriots → a football team- the Beatles → a band- the Ramones → a band- the Marines → a military group- the Navy SEALs → a military group
- Famous buildings and monuments - the White House - the Berlin Wall - the Eiffel Tower - the Jefferson Monument - the Great Wall of China - → Like with geographical features, these mostly have the form descriptor + building type 
- Newspapers - the New York Times - the National Inquirer - the Sunday Post - the Chicago Tribune 
- Organizations - the United Nations - the Internal Revenue Service (IRS) - the Federal Bureau of Investigation (FBI) - the Humane Society - the Girl Scouts - the Audubon Society - the Air Force - the Red Cross 
- Historical time periods - the 1800s - the Reformation - the Renaissance - the 1920s - the Age of Enlightenment - the Turn of the Century 
Tip
Sometimes proper nouns are shortened into acronyms or abbreviations, such as the US (United States) or the UN (United Nations). You should treat these acronyms the same as the full noun. So if the proper noun needs the, then the acronym also needs the.
- ✅ My uncle works for the United Nations. 
- ✅ My uncle works for the UN. 
- ✅ I am visiting New York City next month. 
- ❌ I am visiting the NYC next month. 
When a proper noun requires the definite article, you always use the before it. You cannot use it without an article and you cannot use the indefinite article a/an or any other like that or my.
Let’s look at a couple examples!
✅ I am moving to the United States.
❌ I am moving to United States.
✅ I live very close to the Pacific Ocean.
❌ I live very close to that Pacific Ocean.
✅ Tonight we are eating dinner with the Garcias.
❌ Tonight we are eating dinner with some Garcias.
Is ‘the’ capitalized in a proper noun?
When a proper noun starts with the, we do not usually capitalize the unless it is at the beginning of a sentence.
Exception!
At the start of a title for a book, movie, song, etc. the word the is capitalized, e.g. The Tale of Two Cities. In titles, other function words like of, a, in, or the, are not capitalized.
What is a proper adjective?
Proper nouns can sometimes be turned into proper adjectives when they are used to describe another noun.
Nouns that are described with proper adjectives will always have the in front of them, even if they are not proper nouns. For example:
Last year I went to Hawaii.
Last year I went to the Hawaiian Islands.
I work for the Hawaiian government.
