What is a Proper Noun?

A proper noun is a word used to identify a unique, specific person, place, thing, or organization. It always begins with a capital letter, regardless of its position in a sentence. Proper nouns distinguish particular entities from others within a category.

Rules for Proper Nouns:

  1. Capitalization: Proper nouns are always capitalized. This rule applies to the first letter of the noun, regardless of its position within a sentence.

  2. Individual Identification: Proper nouns are used to name specific individuals, such as people’s names (e.g., John, Mary), specific locations (e.g., Paris, Mount Everest), unique organizations (e.g., Apple Inc., United Nations), and specific titles or trademarks (e.g., Coca-Cola, Harry Potter).

  3. No Plural Form: Proper nouns do not have a plural form unless they represent a group of people or places. For example, “the Johnsons” refers to multiple individuals with the last name Johnson.

  4. No Articles: Proper nouns are not preceded by articles like “a,” “an,” or “the” unless they are part of a specific title or phrase. For instance, “The Eiffel Tower” or “The Beatles.”
