Expert writing Tips
Best practice
Always use the grammatically correct form, "such a thing". Ensure that the article "a" agrees with the noun it precedes. Remember "an" is used before vowel sounds, while "a" is used before consonant sounds. "Thing" begins with a consonant sound, thus "a" is the correct article.
Common error
Avoid using "an" before words that start with a consonant sound. The correct phrase is "such a thing," not "such an thing". Listen to the pronunciation of the word following "such" to determine whether "a" or "an" is appropriate.
