Choosing between a hilarious and an hilarious can be confusing because the word hilarious begins with the letter h and English articles are sometimes difficult to choose based on spelling alone. However, the important factor is not the letter itself but the sound that follows the article.
In standard modern English, a hilarious is the correct form because the h in hilarious is pronounced. We therefore use a before it, just as we say a happy person or a helpful teacher. An hilarious is generally considered nonstandard in contemporary English, although it can occasionally be found in older writing or varieties where the initial h is not pronounced.
Quick Answer
The correct form is a hilarious, not an hilarious, in standard modern English.
- ✅ a hilarious joke
- ✅ a hilarious story
- ✅ a hilarious movie
- ❌ an hilarious joke
- ❌ an hilarious story
The reason is simple: hilarious begins with a pronounced h sound, which is a consonant sound.
Why People Confuse It
People often confuse a hilarious and an hilarious because they may think the choice between a and an depends on the first letter.
It actually depends on the sound.
Compare:
- a hilarious → starts with /h/ → consonant sound
- an amazing → starts with /ə/ → vowel sound
- a useful → starts with /j/ → consonant sound
- an honest → starts with a vowel sound because the h is silent
So the correct question is not:
“Does the word start with a vowel letter?”
Instead, ask:
“Does the word start with a vowel sound?”
A Hilarious
A hilarious is the standard and correct form when hilarious is followed by a singular countable noun.
Examples:
- a hilarious joke
- a hilarious story
- a hilarious movie
- a hilarious person
- a hilarious situation
Example Sentences
- She told a hilarious story about her childhood.
- We watched a hilarious movie last night.
- He made a hilarious joke during the meeting.
- That was a hilarious mistake.
- They shared a hilarious video online.
You can also use a hilarious when describing a person:
She is a hilarious comedian.
Here, a is required because hilarious begins with a consonant sound.
An Hilarious
An hilarious is generally not the standard choice in contemporary English.
❌ She told an hilarious story.
✅ She told a hilarious story.
❌ It was an hilarious movie.
✅ It was a hilarious movie.
The form an hilarious may occasionally appear in older texts or in speech varieties in which the initial h is dropped. However, if you’re writing standard American or British English today, a hilarious is the natural choice.

When to Use Each
Use “a hilarious”
Use a hilarious whenever you describe a singular countable noun with hilarious.
Examples:

What about “an hilarious”?
In standard modern English, avoid an hilarious.

Common Mistakes
Mistake 1: Choosing “an” because of the spelling
❌ an hilarious joke
✅ a hilarious joke
The word begins with the consonant sound /h/, so a is required.
Mistake 2: Thinking every word beginning with “h” takes “a”
This isn’t always true.
Some words beginning with h have a silent h:
- an honest person
- an hour
- an honor
Compare:
- a hilarious person
- an honest person
The difference is pronunciation.
Mistake 3: Thinking “an hilarious” sounds more formal
It doesn’t. In contemporary standard English, a hilarious is the normal form.
Mistake 4: Looking only at letters
English articles are determined by sound, not simply by the first written letter.
Memory Trick
Use this simple rule:
A = consonant sound
An = vowel sound
Since hilarious starts with an audible h:
hilarious → a hilarious
Compare:
a hilarious story
an amazing story
Remember:
Hear the H → use A.
American vs British English
Both American and British English normally use a hilarious.
Examples:
- American English: a hilarious movie
- British English: a hilarious movie
The difference is not normally regional. It comes from the pronunciation of the word hilarious.
In both varieties, the initial h is normally pronounced, so a is the appropriate indefinite article.
Similar Words
The same a/an principle applies to many other commonly confused expressions:
- a historic event / an historic event
- a hotel / an hotel
- a honest ❌ / an honest ✅
- a hour ❌ / an hour ✅
- a useful idea / an useful ❌
- a university / an university ❌
- an unusual idea / a unusual ❌
The key is always the initial sound.
Final Verdict
A hilarious is the correct choice in standard modern English. Because hilarious begins with a clearly pronounced h sound, it takes the indefinite article a.
An hilarious is generally not used in contemporary standard English, although it may occasionally appear in older writing or dialectal usage where the initial h is not pronounced.
The easiest way to remember the rule is to focus on pronunciation rather than spelling. If you hear the /h/ sound in hilarious, use a.
