Ojibwa: Algonquian people of North America living along the shores of Lake Superior, 1700, from Ojibwa O'chepe'wag "plaited shoes," in reference to their puckered moccasins, which were unlike those of neighboring tribes. The older form in English is Chippewa, which is usually retained in U.S., but since c. 1850 Canadian English has taken up the more phonetically correct Ojibwa, and as a result the two forms of the word have begun to be used in reference to slightly differing groups in the two countries. Some modern Chippewas prefer anishinaabe, which means "original people."
OK: 1839, only survivor of a slang fad in Boston and New York c. 1838-9 for abbreviations of common phrases with deliberate, jocular misspellings (such as K.G. for "no go," as if spelled "know go;" N.C. for "'nuff ced;" K.Y. for "know yuse").

Probably further popularized by use as an election slogan by the O.K. Club, New York boosters of Democratic president Martin Van Buren's 1840 re-election bid, in allusion to his nickname Old Kinderhook, from his birth in the N.Y. village of Kinderhook. Van Buren lost, the word stuck, in part because it filled a need for a quick way to write an approval on a document, bill, etc. Spelled out as okeh, 1919, by Woodrow Wilson, on assumption that it represented Choctaw okeh "it is so" (a theory which lacks historical documentation); this was ousted quickly by okay after the appearance of that form in 1929.
