Expert writing Tips

Best practice

Always include a verb (like "is", "was", "feels", "seemed") after "he" to create a grammatically correct sentence when expressing certainty. For example, use "he is certain that" instead of "he certain that".

Common error

Avoid omitting the verb "to be" (is, was, etc.) when expressing someone's certainty. Saying "he certain that" is grammatically incorrect; instead, use "he is certain that" or "he was certain that."
