Pronouns must match nouns

Do not use two negatives together
Example: I don’t have any money

7. Use articles correctly (a, an, the)

Based on sound and specificity
Example: An apple, a book, the sun

8. Place adjectives correctly

Usually before the noun
Example: A beautiful house

9. Use adverbs properly

Modify verbs, adjectives, or other adverbs
Example: She runs quickly

10. Maintain sentence clarity and structure
