What are the rules for using modifiers with proper nouns?

The rules for using modifiers with proper nouns are as follows:

1. Modifiers should be placed before the proper noun they are modifying. For example, "the famous artist Picasso" or "the beautiful city Paris."

2. Proper nouns should not be modified with comparative or superlative forms. For example, it is incorrect to say "the most famous artist Picasso" or "the biggest city Paris." Instead, use phrases like "one of the most famous artists, Picasso" or "a very large city, Paris."

3. Adjectives used as modifiers should agree in number and gender with the proper noun they are modifying. For example, "the talented actors" or "the successful businesswomen."

4. Proper nouns that are possessive should be modified using possessive forms. For example, "John's car" or "Mary's house."

5. When using multiple modifiers with a proper noun, they should be placed in a specific order: opinion, size, age, shape, color, origin, material, and purpose. For example, "the beautiful, old, round, red, Italian, wooden, dining table."

Overall, modifiers should be used to provide additional information or description to proper nouns, while following these rules for clarity and correctness.
