Etymology

Origin of seafood

An Americanism dating back to 1830–40

Explanation

Seafood refers to water-dwelling animals that people kill and eat, such as fish, shrimp, or even octopuses. Seafood is not what happens to your friend if you open your mouth while you’re chewing. Do you enjoy fish and chips? Fried clams? Tuna fish sandwiches? All of these qualify as seafood. It was once fairly common to think of larger sea creatures including whales and dolphins as seafood too, although fewer people eat these animals today. The term seafood can also be used for fish that live in lakes and rivers, rather than oceans; and edible seaweeds like kelp.
