Expert writing Tips
Best practice
When comparing light sources, ensure that the context makes it clear whether you're referring to literal brightness or a figurative sense of brilliance or clarity. If comparing intelligence, consider using alternatives like "not as intelligent" or "less sharp" for better clarity.
Common error
Don't assume the context is always clear. If you state that someone is "not as bright", clarify if you mean their intelligence or their outlook on life. Misunderstandings happen when the intended meaning isn't explicitly stated.
