Expert writing Tips
Best practice
When using "true reason why", ensure it adds emphasis and isn't merely redundant. If a simpler phrasing like "reason" or "cause" suffices, prefer that for conciseness.
Common error
Avoid using "true reason why" in situations where the 'true' aspect is already implied. Overuse can make your writing sound verbose. Instead, opt for a simpler construction like "the reason" or "the cause" if the context makes it clear that you're referring to the actual or primary reason.
