The adjective mammoth is a great way to describe something really, really big, like those huge woolly elephants they’re still finding in the melting glaciers.

The word mammoth is a pretty new one, dating back only to around 1700. It was first only a noun from the Russian word mammot, meaning “earth,” and used to name the newly-discovered fossilized creature that was thought to have burrowed in the earth like a mole. The word, a rare Russian contribution to English, was not used as an adjective until around 1800 — notably when President Thomas Jefferson used it to describe a very large cheese.
