Etymology

Origin of whale¹

First recorded before 900; Middle English; Old English hwæl; cognate with German Wal- in Walfisch, Old Norse hvalr; akin to Latin squalus, a kind of fish; 2005–10 whale ¹ for defs. 6, 7 (from the consideration of the victim as a “big fish/phish”)

Origin of whale²

First recorded in 1780–90; origin uncertain

Explanation

A whale is a large mammal that lives in the ocean. Whales need to breathe air periodically, and the blowholes on their heads help them do this. Blue whales are the largest animals that ever lived — they're even bigger than the largest dinosaurs were! The Old English root of whale means both "whale" and "walrus," although these two marine animals are quite different from each other. While some whales grow to be only ten feet long, many whales are enormous. The informal phrase "a whale of a" comes from the idea that whales are impressive, and you can use it for things (or people) that really distinguish themselves: "Wow, this is a whale of a party!"
