Some people may tell you that there are far more than 10 rules of capitalization in English, and with everything that you have to remember, that may be true. Others say that there are just three rules, and they are also correct. The truth is that, depending on how you organize the rules, the rules of capitalization may be many or few.
Most of the things we capitalize in English are what we call proper nouns. They are the names of specific, unique things.
Capitals are not used for articles (a, an, the) or prepositions (of, on, for, in, to, with, etc.).
1. Names or titles of people
This one may seem obvious, but there’s also a catch. Of course, you capitalize the first letters of a person’s first, middle and last names (John Quincy Adams), but you also capitalize suffixes (Jr., the Great, Princess of Power, etc.) and titles.
Titles can be as simple as Mr., Mrs. or Dr., but they also apply to situations wherein you address a person by his or her position as though it were part of their name. For example, when we talk about President Lincoln, we are using his role as though it were a title not a job description. However, we wouldn’t capitalize the word president if it wasn't being used as a title. For example: "During the Civil War, Abraham Lincoln was the president of the United States."
When capitalizing general job titles look at the position of the job title in the sentence in reference to the person's name. This will help you know if it should be capitalized or not.
For example: "Dr. Rogers was the cardiac surgeon on call." "While I was an intern I got to shadow Senior Marketing Director Sam Jones for a day."
2. Names of mountains, mountain ranges, hills and volcanoes
Again, we’re talking about specific places. The word ‘hill’ is not a proper noun, but Gellert Hill is because it’s the name of one specific hill. Use a capital letter to begin each word in the name of a mountain (Mt. Olympus), mountain range (the Appalachians), hill (San Juan Hill) or volcano (Mt. Vesuvius).
3. Names of bodies of water (rivers, lakes, oceans, seas, streams and creeks)
From here, it gets pretty easy. The same rules that apply to mountain names also apply to water names. A river is just a river, but the Mississippi River is a proper noun and must be capitalized, just like Lake Erie, the Indian Ocean and the Dead Sea.
4. Names of buildings, monuments, bridges and tunnels
5. Street names
Capitalize both the actual name part of the name (Capital) and the road part of the name (Boulevard); both are necessary for forming the entire name of the street (Capital Boulevard).
6. Schools, colleges and universities
All of the words in the name of the educational institution should be capitalized. For example, Harvard University, Wilkesboro Elementary School, Cape Fear Community College.
7. Political divisions (continents, regions, countries, states, counties, cities and towns)
As is the case with regions of a country, the divisions may not always be political, but you get the idea. When you refer to New England, the Midwest, the Pacific Northwest or the South as a region (as opposed to a compass direction), you capitalize it. Also, continents (South America), countries (Belgium), states (Wisconsin), counties (Prince William County), cities (London) and towns (Lizard Lick) get capitalized.
8. Titles of books, movies, magazines, newspapers, articles, songs, plays and works of art
This one’s a little confusing. Articles, prepositions, and conjunctions are not generally capitalized in title case, only principal words are. However, the first letter of a work of art is always capitalized even if it's an article, preposition or conjunction. For example: The Glass Menagerie, A Few Good Men, Of Mice and Men. The last word of these titles always receives a capital too (Fools Rush In).
9. The first letter in a sentence
The last two rules are easy. Always capitalize the first letter of a sentence. If the sentence is a quotation within a larger sentence, capitalize it, but only if it’s a complete sentence. If it’s merely a phrase that fits neatly into the larger sentence, it does not require capitalization. Study the following two examples for clarification:
10. The pronoun I
It’s only necessary to capitalize other pronouns when they begin a sentence, but "I" is always capitalized.
How can you possibly remember all these rules? Well, first of all, you should ask yourself three questions:
And if you want to remember all the specific categories, try memorizing one of the following sentences.
The first letter of each word stands for a category:
And there you have it. Whether you think of English as having 10 rules of capitalization, 30, or just three, you should now be able to remember them all.
