What is Upper Case?
Upper case refers to the use of capital letters in writing. It’s a fundamental aspect of grammar and punctuation, essential for organizing text and ensuring clarity. Capital letters are typically used at the beginning of sentences, for proper nouns, and for emphasis.
Key Concepts of Capitalization
Understanding when to use upper case is vital. Key areas include:
- Starting sentences: The first word of every sentence begins with a capital letter.
- Proper Nouns: Names of specific people, places, organizations, and sometimes things are capitalized. Examples include John, London, and Google.
- Titles: Titles of books, movies, and articles are often capitalized in a style called title case.
- Acronyms and Initialisms: Abbreviations formed from initial letters are usually in upper case, such as NASA or FBI.
