Expert writing Tips

Best practice

When using "had demonstrated", ensure the context clearly indicates what was demonstrated and the impact or consequence of that demonstration. This adds clarity and strength to your writing.

Common error

Avoid using "showed" as a direct substitute for "had demonstrated" in formal contexts where you want to emphasize proven ability or evidence. While "showed" is simpler, "had demonstrated" adds a layer of formality and emphasis on the proven nature of the action.
