What Is Capitalization?
There are many rules you must follow when writing in the English language. These rules generally fall under the category of grammar. One of the most important concepts in grammar deals with capitalization.
When you first learn the alphabet, you learn the lowercase form of each letter, as well as the capital form. Capitalization, then, is using the capital form of the first letter in a word, while all the other letters in the word remain lowercase. There are four main rules of capitalization you will learn in this lesson. First, let's discuss why capitalization is important.
Why Capitalize?
All the rules in standard grammar serve some sort of purpose that always relates to conveying a clear meaning. Capitalization's purpose is to help show the reader the importance of different words. For example, let's look at how capitalization can show importance with some nouns. Remember, a noun is a person, place or thing.
Look at these two phrases: 'The White House' and 'the white house.' Because the first phrase is capitalized, you as the reader know it is more important. Capitalized, it refers to the house the President of the United States lives in; lowercase, it refers to any house that is white. In this example, you can see how capitalization shows the reader the clear meaning of the words. Now that you know what capitalization is and its purpose, let's look at the rules for capitalization.
Proper Nouns
The first rule requires you to capitalize all proper nouns. Proper nouns are nouns that represent a specific person, place or thing. The opposite is a common noun, which includes all words for the general name of the person, place or thing.
For example, look at this sentence: 'I plan on going to a university.' The word 'university' is a common noun. University does not refer to any specific school, just any higher learning facility. On the other hand, look at this sentence: 'I plan on going to Harvard University.' Now university is a proper noun, since it points to a specific school.
'The White House' example we looked at earlier also follows this rule. When you capitalize this phrase, you are referring to the specific house the president lives in, not any house painted white. Some other proper nouns include political divisions, such as states and countries, or historical movements. Names of these words are considered proper nouns. Examples of historical movements include the Reformation or Renaissance because each is a significant period in history.
In addition, when a common noun is made into a proper noun, note that all parts of the name are capitalized. In the 'Harvard University' example, 'Harvard' is not the only word capitalized; 'university' is as well, since it is now a part of the name of that specific school. This rule can also be seen every day on the roads you travel to and from school or work. 'Main Street,' 'Pennsylvania Avenue' or 'Route 182' all have capitalized common nouns because they are now part of the name of the proper noun.
