Expert writing Tips
Best practice
When using a comparison, ensure the adjective you select is a well-understood and standard descriptor. If your reader doesn't understand what the comparison is alluding to, they will struggle to grasp the analogy.
Common error
Avoid using adjectives without a clear, established meaning in comparative constructions. If your reader cannot easily relate to the adjective used in the comparison, they will likely misinterpret the intended message or fail to understand it altogether.
