What is a proper noun​

Answer 1

Answer:

Explanation:

A proper noun is a noun that identifies a single entity and is used to refer to that entity, such as London, Jupiter, Sarah, or Microsoft, as distinguished from a common noun, which is a noun that refers to a class of entities and may be used when referring to instances of a specific class.

Answer 2

Answer:

A proper noun is the name given to something to make it more specific (e.g., Johnathan, Ollie, New York, Monday). ... Proper nouns contrast with common nouns, which are the words for something (e.g., boy, dog, city, day). Common nouns are written with a capital letter only when they start a sentence.
