If you’ve ever wondered whether to write an hilarious or a hilarious, you’re not alone. It’s a classic English question and the answer depends on how the word sounds, not just how it’s spelled.
Let’s clear it up in a simple, practical way.
Quick Answer: An Hilarious or A Hilarious
- A hilarious ✅ Correct in modern English
- An hilarious ⚠️ Rare, old-fashioned
- Use a hilarious in almost all situations
Example:
- That was a hilarious joke.
Why “A Hilarious” Is Correct
The rule for a vs an depends on sound, not spelling:
- Use a before a consonant sound
- Use an before a vowel sound
The word hilarious starts with a clear “h” sound (hi-LAIR-ee-us), which is a consonant sound.
So:
- a hilarious story ✅
- an hilarious story ❌ (in modern usage)
What About “An Hilarious”?
You might occasionally see an hilarious in:
- Very old texts
- Formal or historical writing
- Accents where the “h” is silent
In older British English, some speakers dropped the “h” sound, making it sound like:
- “an ilarious”
But in modern English, the “h” is pronounced, so an hilarious is no longer standard.
A vs An with “H” Words
Here’s a quick guide:
| Word | Correct Form | Reason |
|---|---|---|
| Hilarious | A hilarious | “h” is pronounced |
| Honest | An honest | “h” is silent |
| Hour | An hour | “h” is silent |
| History | A history | “h” is pronounced |
Key Difference Explained Simply
- A hilarious = correct (clear “h” sound)
- An hilarious = outdated or rare
Easy Trick to Remember
Use this simple rule:
👉 Say the word out loud
👉 If you hear the “h” → use a
👉 If the “h” is silent → use an
So:
- hilarious → “h” sound → a hilarious
Common Mistakes People Make

People see “h” and assume “an,” but sound matters more.

Just focus on pronunciation it solves everything.
