an useless
Grammar usage guide and real-world examplesUSAGE SUMMARY
The phrase "an useless" is not correct or usable in written English.
"Useless" is an adjective, and it needs to be followed by a noun. "A/an" is an article used before a noun to indicate that it is singular. Using both together does not make grammatical sense. Instead, you can use the adjective "useless" before a noun without the article, or you can use the article "a/an" before a different adjective. For example: - "That is a useless idea." (adjective + noun) - "That is an idea of little use." (article + adjective + noun) An example sentence using "useless" correctly could be: - "The broken pencil was useless for writing."

Common error
The most common mistake is using "an" before words that start with a consonant sound, such as "useless". Remember that "an" is used before vowel sounds, not just vowels. Avoid errors by pronouncing the word and listening to the initial sound.

FAQs
When should I use 'a' versus 'an'?
Use "a" before words that begin with a consonant sound (e.g., a car, a university) and "an" before words that begin with a vowel sound (e.g., an apple, an hour). It's about the sound, not just the letter. So it's "a university" because 'university' starts with a 'y' sound.
Is it ever correct to say "an useless"?
No, it is not correct. The correct phrasing is "a useless" because the word "useless" begins with a consonant sound, even though "u" is a vowel.
