How do you make shirt into a proper noun?

You can't make "shirt" into a proper noun just by itself. Here's why:

* Proper nouns are specific names of people, places, or things. They are always capitalized.

* Common nouns are general names for people, places, or things. They are not capitalized unless they are at the beginning of a sentence.

Examples:

* Common noun: shirt

* Proper noun: The "Red Shirt" (a specific shirt with a name or brand)

Here's how to turn "shirt" into a proper noun:

1. Give it a unique name or brand:

* "The Red Shirt"

* "My Lucky Shirt"

* "The Levi's Shirt"

2. Use it as part of a name:

* "The Shirt Shop"

* "Shirt's Pizza"

Remember, to make a word a proper noun, it needs to identify a specific, unique item.
