Expert writing Tips

Best practice

Use "would not have" to describe hypothetical situations in the past that did not occur. It's crucial to ensure the preceding clause sets up the necessary condition or scenario. For example: "If I had studied harder, I "would not have" failed the exam."

Common error

Avoid using "would not have" when describing a simple past event without a hypothetical condition. Instead of "I "would not have" went to the store yesterday", use "I did not go to the store yesterday".
