Catalog or Catalogue – Quick Answer

Quick Answer: Both spellings are correct.

Catalog → Preferred in American English. Example: “I ordered a new product from the store catalog.”
Catalogue → Preferred in British English. Example: “The library has an extensive book catalogue.”

💡 Tip: Use the spelling that aligns with your target audience or style guide.

The Origin of Catalog or Catalogue

The word catalogue comes from the Greek “katalogos”, meaning a list or register. It entered English in the late Middle Ages via Latin, retaining the -ue ending commonly found in British English. Over time, American English simplified the spelling to catalog by dropping the final -ue, a trend seen with many British words such as dialogue → dialog and monologue → monolog.

This simplification makes catalog shorter, easier to type, and more common in U.S.-based publications, while catalogue remains traditional in the UK and Commonwealth countries.

British English vs American English Spelling

Feature	American English	British English
Preferred spelling	Catalog	Catalogue
Common in	U.S., Canada (sometimes)	U.K., Australia, India, New Zealand
Example sentence	“Check the store catalog for discounts.”	“The museum catalogue featured rare paintings.”
Usage in digital media	Increasingly catalog	Traditional catalogue

Rule of thumb: Drop the -ue for American audiences; keep it for British audiences.

Which Spelling Should You Use?

The spelling you choose depends on your audience:

U.S. audience: Always use catalog. It looks modern and familiar.
UK/Commonwealth audience: Use catalogue to match traditional spelling and local norms.
Global audience: Both are understood. If unsure, consider your brand or the style guide you follow.

📌 Pro tip: For international business, pick one spelling and stay consistent across all communications.
