1580s, a form of madness (described by ancient writers) in which the afflicted thought he was a wolf, from Greek lykanthropia, from lykanthropos "wolf-man," from lykos "wolf" (see wolf (n.)) + anthrōpos "man" (from PIE root *ner- (2) "man"). Applied to actual transformations of persons (especially witches) into wolves since 1830 (see werewolf).
Middle English manhede, manhode, "state of being human" (early 13c.), from man (n.) + -hood. Sense of "manliness, qualities considered becoming to a man" (variously: "courageous behavior, bravery; courteous behavior, gentility; compassion, kindness") is from c. 1300. Meaning "state of being an adult male" is from late 14c.
Similar words in Old English also were less explicitly masculine: manscipe "humanity, courtesy," literally "man-ship;" mennisclicnes "state of man, humanity, humaneness, human nature" (compare mannish). The more purely "manly" word was werhad "male sex, virility, manhood" (see first element in werewolf).
It forms all or part of: curia; Fergus; triumvir; triumvirate; Weltanschauung; Weltschmerz; werewolf; wergeld; world; virago; virile; virility; virtue; virtuosity; virtuoso; virtuous.
It is the hypothetical source of/evidence for its existence is provided by: Sanskrit virah, Avestan vira-, Latin vir, Lithuanian vyras, Old Irish fer, Welsh gwr, Gothic wair, Old English wer "a man."
Old English husbonda "male head of a household, master of a house, householder," probably from Old Norse husbondi "master of the house," literally "house-dweller," from hus "house" (see house (n.)) + bondi "householder, dweller, freeholder, peasant," from buandi, present participle of bua "to dwell" (from PIE root *bheue- "to be, exist, grow," and compare bond (adj.)).
Slang shortening hubby is attested by 1680s. Beginning late 13c. it replaced Old English wer as "married man (in relation to his wife)" and became the companion word of wife, a sad loss for English poetry. Old English wer, in the broadest sense "man, male person" (from PIE root *wi-ro- "man"), is preserved in werewolf.
Old English woruld, worold "human existence, the affairs of life," also "a long period of time," also "the human race, mankind, humanity," a word peculiar to Germanic languages (cognates: Old Saxon werold, Old Frisian warld, Dutch wereld, Old Norse verold, Old High German weralt, German Welt), with a literal sense of "age of man," from Proto-Germanic *weraldi-, a compound of *wer "man" (Old English wer, still in werewolf; see virile) + *ald "age" (from PIE root *al- (2) "to grow, nourish").
Originally "life on earth, this world (as opposed to the afterlife)," sense extended to "the known world," then to "the physical world in the broadest sense, the universe" (c. 1200). In Old English gospels, the commonest word for "the physical world," was Middangeard (Old Norse Midgard), literally "the middle enclosure" (see yard (n.1)), which is rooted in Germanic cosmology. Greek kosmos in its ecclesiastical sense of "world of people" sometimes was rendered in Gothic as manaseþs, literally "seed of man." The usual Old Norse word was heimr, literally "abode" (see home). Words for "world" in some other Indo-European languages derive from the root for "bottom, foundation" (such as Irish domun, Old Church Slavonic duno, related to English deep); the Lithuanian word is pasaulis, from pa- "under" + saulė "sun."
Original sense in world without end, translating Latin saecula saeculorum, and in worldly. Latin saeculum can mean both "age" and "world," as can Greek aiōn. Meaning "a great quantity or number" is from 1580s. Out of this world "surpassing, marvelous" is from 1928; earlier it meant "dead." World Cup is by 1951; U.S. baseball World Series is by 1893 (originally often World's Series). World power in the geopolitical sense first recorded 1900. World-class is attested from 1950, originally of Olympic athletes.
