Etymology

Origin of ketchup

First recorded in 1705–15; from Malay kəchap “fish sauce,” perhaps from dialectal Chinese kéjāp (Guangdong) or ke-tsiap (Xiamen), akin to Chinese qié “eggplant” + chī “juice”

Explanation

Ketchup is a red, tomato-based condiment. Many people love to slather ketchup on their hamburgers and hotdogs, while others prefer mustard. You can also call ketchup catsup, but either way it's a sweet sauce made of tomatoes and spices. Commercial ketchup tends to have plenty of sugar or other sweeteners, too. Originally ketchup came in different flavors, made from ingredients like walnuts, oysters, or mushrooms, but today the tomato style has become standard. There are several theories about the origin of ketchup, one of which cites the Xiamen Chinese koechiap, "brine of fish."
