Expert writing Tips
Best practice
Use "not" to create a clear contrast or negation in your sentences. This helps to avoid ambiguity and ensures your intended meaning is accurately conveyed.
Common error
Avoid using double negatives (e.g., "I can't not go"), as they often confuse the meaning and can make your writing difficult to understand. Opt for a positive construction, like "I must go", to express the same idea more clearly.
