Expert writing Tips
Best practice
Always use "a" before words that start with a consonant sound, including those that start with a vowel but are pronounced with a consonant sound (e.g., "a university", "a European country").
Common error
Avoid using "an" before words that begin with a consonant sound. While "useable" starts with the vowel 'u', it sounds like "yoo", a consonant sound. Therefore, the correct article is "a", not "an".

FAQs
What is the correct way to say "An useable"?
The correct phrasing is "a usable". The article "a" is used before words that begin with a consonant sound.
Why is "an useable" grammatically incorrect?
The article "an" is used before words that begin with a vowel sound. "Useable" begins with a consonant sound (the 'y' sound), so "a usable" is the correct form.
What are some alternatives to "an useable"?
Depending on the context, you could use phrases like "a practical", "a functional", or "a workable".
Is there a situation where "an" is correct before a word starting with 'u'?
Yes, if the word begins with a vowel sound. For example, "an umbrella" is correct because "umbrella" starts with a vowel sound. However, a word like "useable" has a consonant sound at the beginning (the 'y' sound), thus requiring the article "a".
