Why is the ninth month called September?
"aware, up-to-date," first recorded 1908 in "Saturday Evening Post," but said to be underworld slang, of unknown origin. Variously said to have been the name of "a fabulous detective who operated in Cincinnati" [Louis E. Jackson and C.R. Hellyer, "A Vocabulary of Criminal Slang," 1914] or a saloonkeeper in Chicago who "never quite understood what was going on ... (but) thought he did" ["American Speech," XVI, 154/1]. Taken up by jazz musicians by 1915; hepcat "addict of swing music" is from 1938. With the rise of hip (adj.) by the 1950s, the use of hep ironically became a clue that the speaker was unaware and not up-to-date.
cry of those leading pogroms or attacks on Jews in Europe, 1819 in reference to Jewish explusions by mobs in various German cities in that year (later called the hep-hep riots); perhaps originally the cry of a goatherd, or of a hunter urging on dogs, but popularly said at the time to be acronym of Latin Hierosolyma Est Perdita "Jerusalem is destroyed," which, as H.E.P., supposedly was emblazoned on the banners of medieval recruiters for the Crusades who drew mobs that subsequently turned on local Jewish populations. That such things happened is true enough, but the story about the supposed acronym sounds like folk etymology.
"part of the body where pelvis and thigh join," Old English hype "hip," from Proto-Germanic *hupiz (cf. Dutch heup, German Hüfte, Gothic hups "hip"), from PIE *qeub- "to bend." Hip of a roof is from late 17c.
"seed pod" (especially of wild rose), Old English heope, hiope "seed vessel of the wild rose," from Proto-Germanic *hiup- (cf. dialectal Norwegian hjupa, Old Saxon hiopo, Dutch joop, Old High German hiafo, dialectal German Hiefe, Old English hiopa "briar, bramble").
"informed," 1904, apparently originally in black slang, probably a variant of hep (1), with which it is identical in sense, though it is recorded four years earlier.
exclamation used to introduce a united cheer (cf. hip-hip-hurrah), 1827, earlier hep, cf. German hepp, to animals a cry to attack game, to mobs a cry to attack Jews (see hep (2)); perhaps a natural sound (cf. Latin eho, heus).
The lateral prominence of the pelvis from the waist to the thigh.

in anatomy, the joint between the thighbone (femur) and the pelvis; also the area adjacent to this joint. The hip joint is a ball-and-socket joint; the round head of the femur rests in a cavity (the acetabulum) that allows free rotation of the limb. Amphibians and reptiles have relatively weak pelvic girdles, and the femur extends horizontally. This does not permit efficient resistance to gravity, and the trunks of these animals often rest partially on the ground. In mammals the hip joint allows the femur to drop vertically, thus permitting the animal to hold itself off the ground and leading to specializations for running and leaping. See also pelvic girdle.
