- mammoth (n.)
- 1706, from Russian mammot', probably from Ostyak, a Finno-Ugric language of northern Russia (compare 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 of the cheese wheel, more than 4 feet in diameter, sent to President Jefferson by the ladies of the Baptist congregation in Cheshire, Massachusetts, 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.

- man (v.)
- Old English mannian "to furnish (a fort, ship, etc.) with a company of men," from man (n.). Meaning "to take up a designated position on a ship" is first recorded 1690s. Meaning "behave like a man, act with courage" is from c. 1400. To man (something) out is from 1660s. Related: Manned; manning.
- man (n.)
- Old English man, mann "human being, person (male or female); brave man, hero; servant, vassal," from Proto-Germanic *manwaz (source also of Old Saxon, Swedish, Dutch, Old High German man, German Mann, Old Norse maðr, Danish mand, Gothic manna "man"), from PIE root *man- (1) "man" (source also of Sanskrit manuh, Avestan manu-, Old Church Slavonic mozi, Russian muzh "man, male").
Plural men (German Männer) shows effects of i-mutation. Sometimes connected to root *men- "to think" (see mind), which would make the ground sense of man "one who has intelligence," but not all linguists accept this. Liberman, for instance, writes, "Most probably man 'human being' is a secularized divine name" from Mannus [Tacitus, "Germania," chap. 2], "believed to be the progenitor of the human race."
So I am as he that seythe, 'Come hyddr John, my man.' 
Sense of "adult male" is late (c. 1000); Old English used wer and wif to distinguish the sexes, but wer began to disappear late 13c. and was replaced by man. Universal sense of the word remains in mankind and manslaughter. Similarly, Latin had homo "human being" and vir "adult male human being," but they merged in Vulgar Latin, with homo extended to both senses. A like evolution took place in Slavic languages, and in some of them the word has narrowed to mean "husband." PIE had two stems: *uiHro "freeman" (source of Sanskrit vira-, Lithuanian vyras, Latin vir, Old Irish fer, Gothic wair) and *hner "man," a title more of honor than *uiHro (source of Sanskrit nar-, Armenian ayr, Welsh ner, Greek aner).
