Expert writing Tips
Best practice
Ensure the noun following the phrase is appropriate; while a volcano can be "an inactive" one, it is more commonly described as dormant.
Common error
Avoid using the article "a" before "inactive". Since "inactive" begins with a vowel sound, the correct article is always "an". Writing "a inactive account" is a frequent grammatical slip.
