Word Origin and History for mammoth
1706, from Russian mammot', probably from Ostyak, a Finno-Ugric language of northern Russia (cf. Finnish maa "earth"). Because the remains were dug from the earth, the animal was believed to root like a mole. As an adjective, "gigantic," from 1802; in this sense "the word appears to be originally American" [Thornton, "American Glossary"], and its first uses are in derogatory accounts to the cheese wheel, more than 4 feet in diameter, sent to President Jefferson by the ladies of the Baptist congregation in Cheshire, Mass., as a present, engraved with the motto "Rebellion to tyrants is obedience to God." Federalist editors mocked the affair, and called up the word mammoth (known from Peale's exhibition) to characterize it.
- Any of various extinct elephants of the genus Mammuthus, having long, upwardly curving tusks and thick hair. Mammoths grew to great size and lived throughout the Northern Hemisphere during the Ice Age.
