Expert writing Tips
Best practice
Follow "I realised that" with a complete clause (subject + verb + object) to ensure clarity and avoid ambiguity. For example, "I realised that the meeting had already started."
Common error
Don't use "I realised that" without a clear and specific object of realization. Vague statements diminish the impact. Instead of saying "I realised that something was wrong", specify what was wrong: "I realised that the figures didn't match the report."
