Confused about whether to write catalogued or cataloged?
You’re not alone. Both spellings appear in books, articles, and online, but knowing which to use depends on your audience.
This guide explains the difference, the origins, and the correct usage so you can write confidently in emails, articles, or social media.
Catalogued or Cataloged – Quick Answer
The quick answer is:
- Catalogued → British English spelling.
- Cataloged → American English spelling.
Both are past tense forms of catalog, meaning “to make a systematic list of items.”
Examples:
- British English: The museum catalogued all new acquisitions last week.
- American English: The library cataloged hundreds of books this month.
✅ Key takeaway: Use the version that matches your audience.
The Origin of Cataloged And Catalogued
The word catalog comes from the Greek word katalogos, meaning “a list or register.” The word entered English in the 16th century and has been spelled with minor variations since then.
Historically, British English often added -ue in past tense verbs like catalogued, while American English simplified spellings to -ed (cataloged). This simplification is part of a broader American English trend led by Noah Webster in the early 19th century, aiming to make spelling more logical.
So, the spelling difference isn’t random it reflects a centuries-old evolution in English writing across regions.
