Ever find yourself wondering whether to write catalogue or catalog? You’re not alone! 🧐 This is one of those classic English spelling debates that confuse even experienced writers.
Both versions look correct — and surprisingly, they both are! However, their usage depends on where you are in the world and the style guide you follow.
Although they sound identical, catalogue and catalog serve completely different purposes depending on regional spelling — British vs. American English.
In this guide, we’ll break down what each form means, where it’s used, and how to choose the right one for your audience. By the end, you’ll know exactly which version fits your writing — no confusion, no guesswork! 📖
What Is “Catalogue”?
Catalogue is the British English spelling of the word. It refers to a list or record of items, typically arranged systematically for reference or sale.
Meaning and Usage
A catalogue can be:
- A printed or digital list of products, books, or art pieces.
- A collection of data or descriptions organized in order.
Examples:
- “The museum released a new catalogue of its exhibits.”
- “You can request the university’s course catalogue online.”
- “I browsed the fashion catalogue before ordering.”
Where It’s Used
- 🇬🇧 United Kingdom
- 🇨🇦 Canada
- 🇦🇺 Australia
- 🇳🇿 New Zealand
These regions prefer traditional spellings that include -ogue endings (like dialogue, monologue, analogue).
What Is “Catalog”?
Catalog is the American English spelling of the same word.
It means exactly the same thing as catalogue — a list or organized collection — but is shorter and more streamlined.
Meaning and Usage
Examples:
- “The library’s digital catalog helps you find books easily.”
- “Our spring catalog features new clothing arrivals.”
- “He works on maintaining the company’s product catalog.”
Where It’s Used
- 🇺🇸 United States
- Occasionally in tech and business contexts worldwide, due to American software standards.
Origin of Simplification
During the 19th and 20th centuries, American lexicographer Noah Webster simplified many British spellings to make them more phonetic — removing unnecessary letters like “-ue” and “-ogue.”
That’s how catalogue became catalog in American English, much like:
- dialogue → dialog
- analogue → analog
- colour → color
Key Differences Between “Catalogue” and “Catalog”
| Feature | Catalogue | Catalog |
|---|---|---|
| Region | 🇬🇧 British, Canadian, Australian English | 🇺🇸 American English |
| Spelling Ending | Ends with -ogue | Ends with -og |
| Formality | More traditional or formal | More modern and simplified |
| Usage in Tech | Rare | Common (software, databases, etc.) |
| Examples | “Art catalogue” | “Library catalog” |
💡 Quick Memory Trick:
If you’re writing for the U.K., think of “Vogue” — both end with -ogue.
If you’re writing for the U.S., think of “dog” — short and simple, just like catalog! 🐶
Real-Life Conversation Examples

When to Use “Catalogue” vs “Catalog”
| Context | Use “Catalogue” | Use “Catalog” |
|---|---|---|
| British or Commonwealth writing | ✅ | ❌ |
| American writing | ❌ | ✅ |
| Academic publications (UK) | ✅ | ❌ |
| Tech, database, or software terms | ⚪ Sometimes | ✅ Preferred |
| Marketing or product listings | Depends on audience | Depends on audience |
👉 Rule of Thumb:
- Writing for American audiences → Catalog
- Writing for British or international audiences → Catalogue
If you’re writing for a global online audience, both are understood, but “catalog” is more common in modern web and tech content.
Fun Fact or History Section
Did you know? 📚
The first recorded use of catalogue dates back to the 15th century, derived from the Latin catalogus and Greek katalogos, meaning “a list or register.”
When Noah Webster published his American Dictionary of the English Language (1828), he advocated for shorter spellings to make English more consistent. That’s why words like catalogue → catalog and colour → color became American standards.
Fun twist: Some American universities (like Harvard) still prefer catalogue in formal print materials, showing that tradition never completely fades!
Conclusion
To sum it up: both “catalogue” and “catalog” are correct — the difference lies in geography and style.
Use catalogue if you’re writing for British, Canadian, or Australian readers.
Use catalog if your audience is American or your context is digital or technical.
No matter which one you choose, you’ll be right — as long as you’re consistent!
So next time someone asks, “Is it catalogue or catalog?”, you can confidently say: “Both — it depends on where you are!” 🌍
