In the 1840s telegraph communications via Morse code became a reality on th east coast of the United States. Telegraphers strove to use shortcuts in messages which would clarify the messages and complete them more quickly. To this day a letter k _._ or "dah dit dah" in morse code is transmitted at the end of each completed message, which is a question asking "have you got that ok?". The receiver then transmits an r ._. or "dit dah dit" in response which means, message received ok. The telegraphers paraphrased the k and r to "ok" and "roger" which both remain in the common parlance today. Although other more esoteric origins of "ok" exist, they were not in the common parlance at the time that telegraphers, train conductors and engineers popularized their use in the 1840s. The term spread to England and Continental Europe (even non-english speaking countries)as telegraphy spread to them.

The principal of establishing a "handshake" in communication in this way (utilizing complimentary status bits regarding segments of messages)is used to this day in advanced digital communication devices.

3) Alternate way for one to say that he/she likes something that may be considered 'uncool' to like. By saying that it is 'OK', he/she in no way makes a strong commitment to hteir interest, as 'OK' usually comes with connotations of 'better than expected' and 'not good, not bad.'

OK is a quintessentially American term that has spread from English to many other languages. Its origin was the subject of scholarly debate for many years until Allen Walker Read showed that OK is based on a joke of sorts. OK is first recorded in 1839 but was probably in circulation before that date. During the 1830s there was a humoristic fashion in Boston newspapers to reduce a phrase to initials and supply an explanation in parentheses. Sometimes the abbreviations were misspelled to add to the humor. OK was used in March 1839 as an abbreviation for all correct, the joke being that neither the O nor the K was correct. Originally spelled with periods, this term outlived most similar abbreviations owing to its use in President Martin Van Buren's 1840 campaign for reelection. Because he was born in Kinderhook, New York, Van Buren was nicknamed Old Kinderhook, and the abbreviation proved eminently suitable for political slogans. That same year, an editorial referring to the receipt of a pin with the slogan O.K. had this comment: “frightful letters... significant of the birth-place of Martin Van Buren, old Kinderhook, as also the rallying word of the Democracy of the late election, ‘all correct’.... Those who wear them should bear in mind that it will require their most strenuous exertions... to make all things O.K.”

Said when expressing non-interest during online messaging, in a polite way. Usually said when someone says somethng that you have little interest in hearing about, but dont want to hurt their feelings by saying "shut up" because they'll probably cry.

there are two possible ways this word could have come into our modern language; firstly the greek word "olla kalla" meaning all's good. Also in the american civil war "zero killed" (o.k) meaning the battle was succesful.
"Yo sup my nigga, hows it hangin'"
"aaah..olla kalla"

"the battle was ok no men killed"

Actually, not many people know about it, but OK comes from the greek words Ola Kala (ïëá êáëá)which means everything allright!
