Expert writing Tips

Best practice

When constructing conditional sentences, ensure the correct verb tense and subject-verb agreement. Instead of "if happened", use "if it happened" or "if that happened".

Common error

Avoid using the bare past participle "happened" directly after "if". Always include a subject (e.g., "it", "that", "this") to create a grammatically correct conditional clause.
