Usage

What does capitalization mean? Capitalization is the act of using capital letters. A capital letter (A, B, C, etc.) is a letter of the alphabet that is bigger than the lower case version (e.g., c, o, s) and sometimes styled differently as well (e.g., a, b, q). In English, we use capital letters for several reasons. The most common reasons we use capitalization in English are to begin a sentence and to indicate a proper noun. We capitalize the first letter of the first word of a sentence to show that this is the beginning of the sentence, as in Who took my wallet?This includes complete sentences that are used in quotations, as in Mom said, “We are going to the mall.”We also use capitalization for proper nouns, that is a particular person, place, or thing, like James, New York, or the Library of Congress. Sometimes, though, companies name themselves or their products without any capitalization or with capitalization in the middle of the word (sometimes called camel case), as in adidas, eBay, and WikiAnswers. The pronoun I is always capitalized, no matter where it is used in a sentence, as in He went to the park, but I stayed home.

Etymology

Origin of capitalization

First recorded in 1855–60; capitalize + -ation

Explanation

Capitalization means using capital, or upper-case, letters. Capitalization of place names, family names, and days of the week are all standard in English. Using capital letters at the start of a sentence and capitalizing all the letters in a word for emphasis are both examples of capitalization. Capitalization also means the act of gaining an advantage from some opportunity: "Her capitalization of the voters' frustration made it much easier for her to win the election." The earliest meaning, however, was purely financial, from the sense of capitalize that means "convert financial assets to capital."
