Expert writing Tips
Best practice
Ensure the indefinite article 'an' is always used because 'awful' begins with a vowel sound, regardless of the noun that follows.
Common error
Writers sometimes mistakenly use 'a' before 'awful' because they are focused on the following noun (e.g., 'a awful mistake'). Always match the article to the immediately following word's sound. Additionally, avoid using it in strictly formal scientific reports where more objective terms like 'significant' or 'severe' are preferred.
