The Origin of Ketchup or Catsup
The history of ketchup is more complex than its spelling suggests.
The word is linked to older Asian sauce names. One commonly discussed source is the Hokkien Chinese term kê-tsiap, which refers to a type of fermented fish sauce. The word later traveled through trade and changed as it entered other languages and cultures.
Early versions of ketchup were not necessarily made from tomatoes. They could contain ingredients such as fish, mushrooms, or other foods.
When the sauce became popular in the Western world, different spellings appeared. These included forms such as catchup, catsup, and ketchup.
Tomato ketchup became especially popular later. As recipes changed, the tomato-based version became the familiar condiment many people know today.
The spelling ketchup eventually became dominant in modern English. Catsup survived as a less common variant.
This explains why both forms can be found in dictionaries and historical sources. They developed from a long history of changing recipes, languages, and spellings.
British English vs American English Spelling
There is an important point about ketchup or catsup: this is not mainly a British-versus-American spelling difference.

Today, however, ketchup is the dominant spelling in both British and American English.

| American English | Ketchup | I need some ketchup. |
| British English | Ketchup | Could you pass the ketchup? |
| Canadian English | Ketchup | He added ketchup to his fries. |
