Best practice

When using "a key purpose", ensure that the surrounding context clearly indicates what the purpose is and why it is considered key. For instance, specify the project, action, or policy to which the purpose relates.

Common error

Avoid using "a key purpose" when the purpose you are describing is not truly essential or central. Overusing this phrase can dilute its impact and make your writing sound less credible. Use a more neutral term like "an aim" or "a goal" if the purpose is not paramount.
