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."

Ludwig's WRAP-UP
