A proper noun is a special type of noun that refers to a specific person, place, thing, or idea and always begins with a capital letter. It is the name of someone or something that is unique and distinct. Imagine proper nouns as the celebrities in the world of words – they stand out and are important enough to have their names capitalized!

For example, 'Emma Watson' is a proper noun because it refers to a specific actress. Similarly, 'London' is a proper noun because it denotes a particular city in England. By using capital letters at the beginning of proper nouns, we give them the spotlight they deserve.

Think of proper nouns as the stars of a story – they have their identities and are essential to understanding the narrative. When we use proper nouns, we are being specific and clear about who or what we are talking about.

Proper nouns help us distinguish between 'the dog' and 'Max,' which could be the name of the dog. When you encounter a word that begins with a capital letter, it's likely a proper noun!

So, in summary, proper nouns are like the VIPs of the noun world – they are unique, important, and always get the capital treatment!
