Catalogue or Catalog – Quick Answer
Both catalogue and catalog are correct.
The spelling depends on the type of English you are using.
- Catalog → American English (US)
- Catalogue → British English (UK, Commonwealth)
Simple Examples:
- US English:
Please review the product catalog before ordering. - UK English:
The museum catalogue is available online.
Both words mean the same thing: a list or collection of items, usually organized and described.
The Origin of Catalogue vs Catalog
The word comes from the ancient Greek word katalogos, meaning a list or an enumeration. It passed through Latin and French before entering English.
Originally, English used the longer spelling catalogue, following French influence. This form was standard in Britain and early English writing. When American English began developing its own spelling rules, many words were simplified to make writing more efficient.
Noah Webster, a major influence on American English, promoted shorter spellings. Over time:
- Catalogue stayed common in British English
- Catalog became standard in American English
This shared history explains why both spellings exist and why neither is wrong.
British English vs American English Spelling
The difference between catalogue or catalog follows a familiar pattern in English spelling.
The Rule:
- British English often keeps -ue endings
- American English often drops the -ue
Common Examples:
- Catalogue (UK) → Catalog (US)
- Dialogue (UK) → Dialog (US, less common but accepted)
- Monologue (UK) → Monolog (US, rare but valid)
