What is a Proper Noun?

Proper Noun Definition: A Proper Noun is the specific name of a particular person, place, or thing, and it always begins with a capital letter. In English grammar, proper nouns help us talk about unique names, not general things.

Why are Proper Nouns Important? They make your writing and speaking clear and precise. Instead of saying "a city," you can say "Paris." Instead of "a company," you can say "Google." This helps your listener or reader know exactly who or what you mean.

Function in Grammar

Proper nouns are used to name unique people, places, organizations, days, months, and more. They are a sub-type of noun, and the opposite of common nouns, which refer to general items or categories.

• Proper Noun: Google, India, Monday
• Common Noun: company, country, day

Proper Noun vs Common Noun: Proper nouns are specific (e.g., Amazon River), while common nouns are general (e.g., river).

Examples of Proper Nouns in Sentences
