Expert writing Tips

Best practice

Always use the grammatically correct form "a usable" instead of "an useable". The article "a" should precede words that begin with a consonant sound.

Common error

Avoid using "an" before words starting with a consonant sound, even if the first letter is a vowel that's pronounced as a consonant (e.g., "a university", not "an university"). Always double-check the pronunciation.
