A proper noun is a noun used as the name of a particular person, place, organization, or thing. Amira, London, Microsoft, and Mount Everest are examples of proper nouns and proper names.
On Thursday, Farah visited the British Museum.
Thursday names a day of the week, Farah names a person, and the British Museum is the name of an institution. All are examples of naming expressions in English.
Examples of Proper Nouns
Proper nouns and names appear in many parts of everyday language, from people’s names and geographical places to organizations and creative works.
| What is named | Examples |
|---|---|
| People | Maya, William Shakespeare, Dr. Patel |
| Cities and countries | Edinburgh, Canada, South Africa |
| Geographical features | Mount Fuji, the Pacific Ocean, Lake Michigan |
| Organizations and institutions | Oxford University, the United Nations, the World Health Organization |
| Brands and products | Samsung, Toyota, iPhone |
| Days and months | Wednesday, September, December |
| Holidays and festivals | Christmas, Diwali, Eid al-Fitr |
| Languages | English, Arabic, Japanese |
| Historical events and periods | World War II, the Great Depression, the Middle Ages |
| Books and creative works | The Secret Garden, Pride and Prejudice, Star Wars |
Some of these names contain words that are ordinary nouns on their own. For example, university and ocean are common nouns, but they can form part of a complete proper name.
What Makes a Noun Proper?
A noun is proper because it functions as a name, not simply because it refers to someone or something specific.
Compare:
I visited the museum near the river.
I visited the British Museum.
The first sentence may refer to one particular museum, but museum remains a common noun. In the second, the British Museum is the institution’s established name.
A similar distinction applies to people. The doctor who treated my brother identifies a particular person, but doctor is still a common noun.
A name such as Dr. Patel, by contrast, identifies someone through a proper name and professional title.
This is an important difference between common nouns and proper nouns. Common nouns can refer to identifiable people and places without functioning as names.
Capitalization Rules for Proper Nouns
Proper nouns normally begin with capital letters, even in the middle of a sentence.
We spent the weekend in Edinburgh.
Edinburgh is capitalized because it is a city name.
There are exceptions to the usual spelling pattern. Some brands and products have established forms such as iPhone and eBay, which should be preserved.
Capital letters can also appear for reasons unrelated to proper nouns, including sentence position and title capitalization.
Names Containing Multiple Words
Not every word in a multiword name begins with a capital letter.
She applied to the University of Edinburgh.
The documents were sent to the Bank of England.
Both are proper names, although of remains lowercase.
The spelling of publication names can differ as well. The newspaper title The New York Times begins with a capitalized The, while we normally write the United Nations with a lowercase article in the middle of a sentence.
Use the established spelling of the name rather than applying one capitalization pattern to every expression.
Professional Titles and Family Names
Professional titles are generally lowercase when they describe someone’s job or position.
The professor explained the results after the lecture.
When a title appears directly before a person’s name as part of a name-and-title expression, it is normally capitalized.
Professor Shah explained the results after the lecture.
Family terms can work in a similar way, depending on how they are used.
| Sentence | How mother is used |
|---|---|
| My mother called yesterday. | Common noun naming a family relationship |
| Mother called yesterday. | Family term used in place of a personal name |
| Mother Teresa devoted her life to helping others. | Title used as part of an established name |
In my mother, the word describes a relationship. When Mother is used as a form of address or in place of a personal name, it is conventionally capitalized.
These uses are different from simply referring to a particular family member.
Days, Months, Holidays, and Seasons
Days of the week, months, and named holidays are capitalized.
Our next appointment is on Tuesday in November.
The family returned home before Diwali.
Seasons usually remain lowercase when referring to the times of year.
The garden looks different in autumn.
Here, autumn is a common noun. It would take a capital letter if it began a sentence or appeared in a title or established name that required one.
Geographical Names and Directions
Names of cities, countries, regions, mountains, and other geographical places are capitalized. Ordinary words expressing directions do not necessarily follow the same pattern.
| Sentence | How west is used |
|---|---|
| We drove west after lunch. | Adverb indicating direction |
| The west of the city was flooded. | Common noun referring to an area |
| She moved to West Virginia. | Part of a proper geographical name |
The word’s grammatical function changes across these sentences.
The names of rivers also have their own established forms.
We crossed the Mississippi during our journey.
Mississippi is a proper geographical name. We can also refer to the river near our village without giving that river its name.
Names such as the River Thames in some styles, or the river Thames in others, illustrate why capitalization conventions sometimes differ between geographical naming practices.
Languages, Nationalities, and Proper Adjectives
Names of languages and nationalities are capitalized in English.
Compare:
She is learning Japanese.
They visited a Japanese restaurant.
In the first sentence, Japanese is a noun naming a language. In the second, it is an adjective describing the restaurant.
Both are capitalized, but they perform different grammatical functions. Adjectives such as Japanese, Canadian, and Brazilian are commonly called proper adjectives when they describe nationality or origin.
Do Proper Nouns Take Articles?
Many personal names and geographical names appear without a, an, or the.
Leila moved to Melbourne last year.
They climbed Mount Fuji during their trip.
Other names are normally used with the.
| Usually without the | Usually with the |
|---|---|
| Canada | the Netherlands |
| Mount Fuji | the Himalayas |
| Lake Michigan | the Pacific Ocean |
| Oxford University | the University of Oxford |
Both of the following sentences are natural:
She studied at Oxford University.
She studied at the University of Oxford.
The two forms name the same institution, but their article usage differs.
Names can also take plural forms when the context calls for them. The Patels may refer to members of a family, while two Emmas means two people who share the name Emma.
These are special uses of names, not separate noun classifications.
How to Identify Proper Nouns in a Sentence
Consider:
On Tuesday, Professor Mehta took her students to a science exhibition in Jaipur.
Some words are capitalized because they are names. Others have different reasons for their capitalization.
| Word or expression | Explanation |
|---|---|
| On | Capitalized because it begins the sentence; not a noun |
| Tuesday | Proper noun naming a day |
| Professor Mehta | Professional title and personal name |
| students | Common noun |
| science exhibition | Ordinary noun phrase, not a proper name |
| Jaipur | Proper noun naming a city |
Tuesday and Jaipur are individual proper nouns. Professor Mehta is a complete title-and-name expression.
Although On begins with a capital letter, it is a preposition. Capitalization alone cannot identify a word’s grammatical class.
Practice Identifying Proper Nouns
1. Find the proper nouns
We spent Saturday in York and walked along the river.
Answer: Saturday and York are proper nouns. River is a common noun because it is not being used as part of the river’s name.
2. Identify the names and explain the capitalization
Professor Lewis met the students near the Thames.
Answer: Professor Lewis is a title-and-name expression, and the Thames is a geographical name. Students remains a common noun.
3. Identify the proper names and the common noun
Maya returned from the Philippines in winter.
Answer: Maya and the Philippines are proper names. Winter is a common noun naming a season and is lowercase in this sentence.
