From obsolete Russian ма́мант (mámant), modern ма́монт (mámont), probably from a Uralic word, such as Proto-Mansi *mān-oŋt (“earth horn”). Possibly influenced by behemoth. Adjectival use was popularized in the early 1800s by references to the Cheshire Mammoth Cheese presented to American paleontologist and president Thomas Jefferson.
