Expert writing Tips

Best practice

When describing a physical or emotional state, be specific about the type of weakness. For example, instead of just saying "I felt weak", consider saying "I felt weak and lightheaded" or "I felt emotionally weak and vulnerable" to provide more context.

Common error

Avoid attributing the feeling of weakness to vague reasons. Instead of simply stating "I felt weak, so I stopped", provide a clearer explanation: "I felt weak from lack of sleep, so I stopped to rest."
