Introduction
Is it a hilarious or an hilarious? If you have ever hesitated before writing this phrase, you are not alone. Many English learners find articles confusing because the choice between a and an depends on pronunciation, not simply on the first letter of a word.
The correct phrase in standard English is “a hilarious” when hilarious is followed by a noun, as in “a hilarious joke.” The word hilarious begins with the consonant sound /h/, so it takes the indefinite article a, not an.
For example, you should write “That was a hilarious movie,” not “That was an hilarious movie.”
In this guide, you will learn why a hilarious is correct, how the rules for a vs an work, and how to use hilarious naturally in everyday English. You will also find practical examples, common mistakes, comparison tables, and answers to frequently asked questions.
What Does “Hilarious” Mean?
Hilarious is an adjective that means extremely funny or very amusing. We use it to describe something that makes people laugh a lot.
For example:
- That was a hilarious joke.
- We watched a hilarious movie last night.
- Her story was absolutely hilarious.
- My friend told a hilarious story at dinner.
The word hilarious is stronger than funny. Something funny may make you smile or laugh, while something hilarious usually makes you laugh a great deal.
Is “A Hilarious” or “An Hilarious” Correct?
“A hilarious” is correct when the phrase is followed by a noun or another suitable word.
Examples:
- A hilarious joke
- A hilarious movie
- A hilarious moment
- A hilarious performance
The phrase “an hilarious” is generally incorrect in modern standard English because hilarious begins with a pronounced /h/ sound.
Remember this simple rule:
Use “a” before a consonant sound and “an” before a vowel sound.
The sound matters more than the spelling.
Why Is “A Hilarious” Correct?
The word hilarious begins with the letter h. In standard English pronunciation, that letter represents a consonant sound at the beginning of the word.
Because the initial sound is a consonant, the correct article is a.
- Correct: It was a hilarious story.
- Incorrect in standard modern English: It was an hilarious story.
Compare these examples:
- A hilarious joke
- A happy child
- A helpful teacher
- A historic building
- A humorous story
Each word begins with a pronounced consonant sound, so a is appropriate.
Does the First Letter Always Decide the Article?
No. The choice depends on the first sound, not just the first letter.
For example:
- An hour — the h is silent, so the word begins with a vowel sound.
- A hotel — the h is pronounced, so the word begins with a consonant sound.
- An honest person — the h is silent.
- A hilarious joke — the h is pronounced.
This is why you cannot choose a or an by looking only at spelling.
The Grammar Rule Behind “A” and “An”
The words a and an are called indefinite articles. They appear before singular countable nouns when we refer to something that is not being identified as a specific item.
The choice between them follows a simple pronunciation rule.
Rule 1: Use “A” Before a Consonant Sound
Use a when the next word begins with a consonant sound.
Examples:
- A hilarious movie
- A beautiful garden
- A funny story
- A useful tool
- A university student
Notice that university begins with the letter u, but its opening sound is /j/, like the beginning of yes. That is why we say a university, not an university.
Rule 2: Use “An” Before a Vowel Sound
Use an when the next word begins with a vowel sound.
Examples:
- An apple
- An interesting book
- An honest person
- An hour
- An unusual experience
The words honest and hour begin with a vowel sound because their initial h is silent.
Rule 3: Listen to the First Sound
When you are unsure, pronounce the word aloud.
Ask yourself:
- Does the word begin with a consonant sound?
- Does it begin with a vowel sound?
- Which article sounds natural before it?
For hilarious, the first sound is /h/. Therefore, a hilarious is correct.

Sentence Structure: How to Use “A Hilarious”
The phrase a hilarious usually appears before a singular countable noun. The adjective hilarious describes the noun.
A common sentence pattern is:
Article + adjective + noun
Examples:
- A hilarious joke
- A hilarious video
- A hilarious character
- A hilarious experience
You can use the phrase in several types of sentences.
1. Subject of a Sentence
- A hilarious movie made everyone laugh.
- A hilarious story started the conversation.
- A hilarious performance won the audience’s attention.
Here, the entire noun phrase acts as the subject.
2. Object of a Sentence
- We watched a hilarious movie.
- She shared a hilarious story.
- He told us a hilarious joke.
In these sentences, the noun phrase receives the action of the verb.
3. After the Verb “Be”
- It was a hilarious moment.
- That was a hilarious performance.

The phrase identifies or describes what something was.
4. With More Than One Adjective
You can use hilarious alongside another adjective.
Examples:
- A short, hilarious video
- A clever and hilarious joke
- A wonderfully hilarious scene
The article a comes before the adjective sequence because the first sound in the phrase is the consonant sound in short or clever in the first two examples.
In “a wonderfully hilarious scene,” the article comes before wonderfully, which begins with a consonant sound.

Common Mistakes and Their Corrections
English learners sometimes choose an article based on spelling or use the wrong article before an adjective.
| Incorrect sentence | Correct sentence | Why? |
|---|---|---|
| It was an hilarious joke. | It was a hilarious joke. | The h in hilarious is pronounced. |
| She told an hilarious story. | She told a hilarious story. | Use a before the consonant sound /h/. |
| We watched an hilarious movie. | We watched a hilarious movie. | The adjective begins with a consonant sound. |
| He made a honest mistake. | He made an honest mistake. | The h in honest is silent. |
| She waited for a hour. | She waited for an hour. | The h in hour is silent. |
| It was an funny moment. | It was a funny moment. | Funny begins with a consonant sound. |
Mistake 1: Choosing “An” Because the Word Starts With a Vowel-Like Sound in Your Mind
Some people mistakenly assume that hilarious begins with a vowel sound because it contains the vowel letters i and a.
However, the first sound is what matters. Since the /h/ is pronounced, a hilarious joke is correct.
Mistake 2: Applying the Same Rule to Every Word Starting With “H”
Not every word beginning with h uses a. Some words have a silent h.
For example:
- A hilarious joke
- A hotel room
- An honest answer
- An hour later
The correct choice depends on pronunciation.
Mistake 3: Forgetting the Noun
In many contexts, a hilarious needs a noun after it.
For example:
- Natural: That was a hilarious joke.
- Incomplete in most contexts: That was a hilarious.
The adjective usually describes a noun, so include one when the sentence requires it.
However, an adjective can sometimes be used without a noun when the noun is understood from context. For example, “I thought the first performance was funny, but the second was even more hilarious.” Here, hilarious appears without a noun because it functions as a subject complement.
