bird of prey (Milvus ictinus), Old English cyta "kind of hawk," probably imitative of its cries (compare ciegan "to call," German Kauz "screech owl"). The toy kite first so-called 1660s, from its way of hovering in the air like a bird. The dismissive invitation to go fly a kite is attested by 1942, American English, probably tracing to the popular song of the same name (lyrics by Johnny Burke), sung by Bing Crosby in "The Star Maker" (1939):
Go fly a kite and tie your troubles to the tail
They'll be blown away by a merry gale,
Go fly a kite and toss your worries to the wind

The name also was late 19c. Australian slang for "a traveler's bundle or swag," hence the expression waltzing Matilda "to travel on foot" (by 1889).
In my electorate nearly every man you meet who is not "waltzing Matilda" rides a bicycle. ["Parliamentary Debates," Australia, 1907]
The lyrics of the song of that name, sometimes called the unofficial Australian national anthem, are said to date to 1893.

Old English ofercuman "to reach, overtake," also "to conquer, prevail over," from ofer (see over) + cuman "to come" (see come (v.)).

In reference to mental or chemical force, "to overwhelm, render helpless," it is in late Old English. Meaning "to surmount" (a difficulty or obstacle) is from c. 1200. The Civil Rights anthem "We Shall Overcome" was put together c. 1950s from lyrics from Charles Tindley's spiritual "I'll Overcome Some Day" (1901), and melody from pre-Civil War spiritual "No More Auction Block for Me."

Yankee Doodle (n.)youdaoicibaDictYouDict
popular tune of the American Revolution, apparently written c. 1755 by British Army surgeon Dr. Richard Schuckburgh while campaigning with Amherst's force in upper New York during the French and Indian War. The original verses mocked the colonial troops (see Yankee) serving alongside the regulars, and the Doodle element might have been, or hinted at, the 18c. slang term for "penis." The song naturally was popular with British troops in the colonies during the Revolutionary War, but after the colonials began to win skirmishes with them in 1775, they took the tune as a patriotic prize and re-worked the lyrics. The current version seems to have been written in 1776 by Edward Bangs, a Harvard sophomore who also was a Minuteman.

raggayoudaoicibaDictYouDict
"A style of dance music originating in Jamaica and derived from reggae, in which a DJ improvises lyrics over a sampled or electronic backing track", 1990s: from ragamuffin, because of the style of clothing worn by its followers. More rag from Middle English:A Scandinavian word for ‘tufted’ probably lies behind rag. In lose your rag (early 20th century) ‘to lose your temper’, rag is probably an old slang term for the tongue—the phrase was originally get your rag out. This sense of rag may well be behind the student rag or prank, found from the early 19th century, and the dated verb meaning ‘to tease, play a joke on’. From rags to riches describes someone's rise from a state of extreme poverty to great wealth, as in a fairytale like Cinderella. The concept is ancient, but the phrase was not recorded until the late 19th century, when a play called From Rags to Riches was mentioned in a US newspaper. A group of people regarded as disreputable or undesirable may be described as ragtag and bobtail. Bobtail (early 17th century) was an established term for a horse or dog with a docked tail, but rag and tag (LME of unknown origin) were separate words conveying the same meaning of ‘tattered or ragged clothes’. Putting them together gives you the literal sense of ‘people in ragged clothes together with their dogs and horses’. In one traditional folk song a lady leaves her house, land, and ‘new-wedded lord’ to run away with ‘the raggle-taggle gypsies’. Raggle-taggle (late 19th century) here is an elaboration of ragtag. Similarly ragamuffin is probably an elaboration of rag. The word is found once c.1400 as the name of a devil, but then not until 1586. The 1990s term ragga for a style of dance music is taken from ragamuffin, because of the style of clothing worn by its fans. Rug (mid 16th century), once a name for a type of coarse woollen cloth, is probably from the same root. The sense ‘small carpet’ dates from the early 19th century. So too is rugged (Middle English). ‘Shaggy’ was an early sense of rugged as was ‘rough-coated’ (in descriptions of horses).
