Many English learners are unsure if they should write a hilarious or an hilarious. The confusion comes from the fact that hilarious begins with the letter H, while the article an is often used before words that start with a vowel sound.
The correct choice depends on pronunciation, not simply the first letter of the word. Understanding this rule will help you use English articles more accurately.
Quick Answer
A hilarious is the correct and preferred form in modern English because hilarious begins with a pronounced H sound (/hɪˈleəriəs/). An hilarious is considered old-fashioned and is rarely used in contemporary English.
Why People Confuse It
The confusion happens because English articles depend on sound, not spelling.
- Use a before a consonant sound.
