OK is a word often spoken by almost everybody, BUT can someone tell it stands for WHAT?!!

Okay, OK, or O.K. is a colloquial English word denoting approval, assent, or acknowledgment that has been a loanword from English for many other languages.

Various etymologies have been proposed for okay, but none has been unanimously agreed upon. Most are generally regarded to be unlikely or anachronistic.
=>>There are four proposed etymologies which have received material academic support since the 1960s. They are:

1. the Greek words "Ola Kala" meaning "everything's good" used by Greek rail-road workers in America
2. the acronym of the "comically misspelled" oll korrect
3. the Choctaw word okeh
4. the Wolof and Bantu word waw-kay or the Mande (aka "Mandinke" or "Mandingo") phrase o ke

The ancient englishman of the US where primarily from poorly backgrounds and lacked a proper education so everyone spelled according to sound.

One day I assume someone just decided let's make our language written and basic so everyone understands it. Still to this day British English and US English has different spellings of some words. Examples are most of our "z" are "s" over there. "f" and "ph" sometimes you'll even see "uu" instead of "w"

OK=oll korrect (all correct), mispelled by old English speakers

Here's an insert from wikipedia:
Okay is a term of approval or assent, often written as OK, O.K., ok, okay, okee, or more informally as simply kay, k or kk. Sometimes used with other words, as in "okey, dokey". When used to describe the quality of a thing, it denotes acceptability. However, its usage can also be strongly approving; as with most slang, its usage is determined by context. It could be one of the most widely used words on Earth, since it has spread from English to many other languages.

The historical record shows that "O.K." appeared as an abbreviation for oll korrect (a conscious misspelling of "all correct") in Boston newspapers in 1839, and was reinterpreted as "Old Kinderhook" in the 1840 United States presidential election. Because it is a recent word borne of word play, and because it is so widely used, "O.K." has also invited many folk etymologies. These competing theories are not supported by the historical written record, except in that folk and joke etymologies influenced the true history of the word. Since the 19th century, the word has spread around the world, the "okay" spelling of it first appearing in British writing in the 1860s. Spelled out in full in the 20th century, 'okay' has come to be in everyday use among English speakers, and borrowed by non-English speakers. Occasionally a humorous form okee dokee (or okey dokey) is used, as well as A-ok.

According to languagemonitor.com, "O.K." is the Most Frequently Spoken Word on the Planet.[1]

Etymology: "Oll Korrect" and "Old Kinderhook"
Allen Walker Read conclusively documented the early history of the abbreviation "O.K.", now also spelled "okay", in a series of six articles in the journal American Speech in 1963 and 1964. He tracked the spread and evolution of the word in American newspapers and other written documents, and later its spread to the rest of the world. He also documented controversy surrounding "O.K." and the history of its folk etymologies, both of which are intertwined with the history of the word itself.

The form "O.K." first became popular in Boston newspapers in 1839 as part of a broader fad of forming and employing acronyms, many of them barbarous. Other examples at the time included "G.T.T." for "gone to Texas" and "K.Y." for "know yuse". The general fad may have existed in spoken or informal written American English for a decade or more before its appearance in newspapers. "O.K." was intended as a misspelling of "all correct"; in the first few years it was often published with this gloss. (Note that gloss indicates the spread of a new word.) The gloss was sometimes varied with degraded spelling such as "Oll Korrect" or even "Ole Kurreck". Deliberate word play was associated with the acronym fad and was a yet broader contemporary American fad. In this first phase, "O.K." was spread with the acronym fad from Boston to other American cities.

The first recorded appearance in the first phase was in the Boston Morning Post on March 23, 1839, in the following passage (mostly probably written by editor Charles Gordon Greene):
