The Origin of OK: From Political Slogan to Universal Expression
“OK” is the most widely used English expression in the world. These two simple letters, understood across all language barriers, have become a universal expression of agreement, approval, and confirmation. However, few people know that this seemingly simple expression actually originated from a witty linguistic play in 19th-century America. The origin of “OK” began with a newspaper article in Boston in 1839, spread across America during the 1840 presidential election, and eventually became part of the global linguistic landscape.
The Abbreviation Craze of 1830s America
To understand the birth of “OK,” we first need to know about the unique linguistic culture that flourished in late 1830s America, particularly in Boston. In the summer of 1838, a peculiar trend began among Boston’s young, educated elite. They started deliberately misspelling words and then abbreviating them.[1]
The abbreviations created during this period worked in a similar way to today’s internet memes and neologisms. For example:
- OFM = “our first men”
- NG = “no go” (misspelled as “know go”)
- GT = “gone to Texas”
- SP = “small potatoes”
- KY = “no use” (misspelled as “know yuse”)
- OW = “all right” (misspelled as “oll wright”)
Linguist Allen Walker Read described this phenomenon as a “remarkable vogue.”[2] Young people of the time enjoyed using these abbreviations as slang in conversation, much like how people create shorthand on social media today.
March 23, 1839: The Birth of “OK”
The first printed instance of “O.K.” in history is precisely documented. On March 23, 1839, editor Charles Gordon Greene of The Boston Morning Post published an article satirizing the editorial practices of a rival newspaper, the Providence Journal.[3]
In that article, Greene used the abbreviation “o.k.,” which stood for “oll korrect.” “Oll korrect” was a deliberate misspelling of “all correct.”[4] This was the official debut of “OK.”
However, like many other abbreviations of the time, this one seemed destined to fade away soon. Indeed, as the 1840s arrived, most of the abbreviation craze waned, and expressions like “NG,” “OW,” and “SP” disappeared into history. But “OK” was the exception. Why?
The 1840 Election and “Old Kinderhook”
The reason “OK” survived was politics. In the 1840 U.S. presidential election, a fierce competition unfolded between incumbent President Martin Van Buren, running for reelection, and his rival William Henry Harrison.[5]

Martin Van Buren hailed from a small town in New York called Kinderhook, and his nickname was “Old Kinderhook,” meaning “the old man from Kinderhook.”[6] Van Buren’s supporters came up with the brilliant idea of using the initials “O.K.” from this nickname as a campaign slogan.
During the 1840 election campaign, Van Buren’s supporters organized “O.K. Clubs” across the nation.[7] These clubs leveraged the dual meaning of “Old Kinderhook” and “oll korrect” (all correct). In other words, the message was: “Old Kinderhook is all correct.”

Van Buren himself joined this trend. He began using the abbreviation “O.K.” when signing documents, attempting to strengthen his political brand.[8]
The Election Result and OK’s Victory
Ironically, Martin Van Buren lost the 1840 election. William Henry Harrison won and became president at the oldest age at that time.[9] Van Buren’s political strategy failed, but “OK” triumphed.
In the fervor of the election campaign, the expression “OK” spread across America and began to establish itself as part of everyday language, beyond a mere campaign slogan. “OK” was now widely used to mean “alright,” “agreed,” and “confirmed.”
Allen Walker Read and Uncovering the Truth of “OK”
Interestingly, the true origin of “OK” was long a subject of debate. For decades, various etymological theories were proposed:
- A theory that it derived from the Greek “olla kalla” (all good)
- A theory that it came from the German “Ober-Kommando” (high command)
- A theory that it originated from the Choctaw Native American language
- A theory that it came from West African languages
The person who cleared up this confusion was Allen Walker Read (1906-2002), a linguist at Columbia University.[10] Read first proposed the “Old Kinderhook” theory in 1941, and from 1963 to 1964, published a series of six papers in the journal American Speech that definitively clarified the etymology of “OK.”[11]
Read’s research traced the original 1839 Boston Morning Post article, documented the late 1830s abbreviation craze, and systematically proved how “OK” became popularized during the 1840 election. His research was immediately recognized by the academic community, and today most dictionaries adopt Read’s etymology without reservation.[12]
The Economist called this research the “pinnacle of Read’s career,” but Read himself modestly stated it was merely “a pleasant digression from my main work.”[13]
The Globalization of “OK”
Several technological and social factors contributed to “OK” becoming more than just American slang and evolving into a global expression.
The Telegraph and Morse Code
In the mid-19th century, the development of telegraph technology played an important role in the spread of “OK.” After Samuel Morse sent the first telegraph message in 1844, the telegraph system rapidly expanded across America and the world. By 1866, a transatlantic telegraph cable was laid connecting America to Europe.[14]
Brevity was key in telegraph communication. Sending long messages was expensive and time-consuming, so short abbreviations were preferred. “OK” was the perfect abbreviation, expressing confirmation and agreement in just two letters.
In 1865, the International Telegraph Union was established to standardize international communications.[15] By the late 19th century, Morse code had become the international language of electrical communication, and “OK” spread worldwide through this international communication network.
The 20th Century: Popular Culture and Globalization
Entering the 20th century, “OK” became an export of American popular culture. Through Hollywood films, pop music, and later the internet and social media, “OK” penetrated nearly every linguistic sphere.
Today, “OK” is used in various forms:
- Notation: OK, O.K., ok, okay
- Hand gesture: The gesture of forming a circle with thumb and index finger (though this gesture can have different meanings in some cultures and requires caution)
- Digital age: 👌 emoji, “k”, “okay”, “okk” and other variations

Naturalization Across the English-Speaking World
From the English-speaking world’s own perspective, the most striking thing about “OK” is how completely the word has been naturalized across regional Englishes that did not invent it. By the 1860s, just over twenty years after the Boston Morning Post coinage, “OK” was already in regular use in British print, and the Oxford English Dictionary granted it an entry before the end of the nineteenth century.[16] British, Australian, and South African English absorbed the term without ever treating it as a noticeable Americanism — a rare distinction, given that words such as “elevator,” “trunk,” or “cookie” still mark a speaker as American in much of the Commonwealth. Aviation reinforced the habit: the Royal Air Force adopted “Wilco” and “Roger” for formal radio confirmation, but pilots in everyday speech already defaulted to “OK,” and the post-war NATO procedure-words list preserved that convention.[17] The result is one of the few twentieth-century coinages that no native English speaker, anywhere, registers as foreign — a status few words of any era have achieved.
Linguistic Characteristics of “OK”
Why has “OK” spread so successfully worldwide? Linguists point to the following characteristics:
- Conciseness: Conveys complete meaning in just two letters (or two syllables).
- Ease of pronunciation: A sound combination that’s easy to pronounce in most languages.
- Semantic flexibility: Usable in various contexts such as “agreement,” “confirmation,” “understanding,” “alright.”
- Positive nuance: Contains neutral or positive meaning, not negative.
- Cultural neutrality: A universal expression not tied to any specific culture or religion.
Modern “OK”
In the 21st century today, “OK” has become more than just a word—it’s a cultural phenomenon. This expression:
- Is used as a standard confirmation signal in international aviation, maritime, and space communications.
- Is the standard label for confirmation buttons in computer interfaces (“OK” button).
- Has been borrowed and used in nearly every language worldwide.
In Korean, it’s widely used as “오케이” or simply “OK”; in Japanese as “オーケー” (ōkē); in Chinese alongside “OK” or “好的” (hǎo de).
Conclusion
The most paradoxical fact in the history of “OK” is that this expression survived thanks to a failed political campaign. Van Buren lost the 1840 election, the nickname “Old Kinderhook” was forgotten, and the “O.K. Club” organization faded into history. Yet the two letters that campaign had scattered across the nation lived on. Politics was defeated, but language won.
This trajectory is difficult to explain as mere linguistic coincidence. Among the 1838 Boston slang expressions, “NG”, “OW”, and “SP” quickly perished, while “OK” survived because three coincidences converged. First, its pronunciation was unusually easy: the simple vowel-consonant combination could be naturally pronounced even by speakers from entirely different language systems. Second, the telegraph — a technological infrastructure — was spreading at precisely this moment, explosively increasing the demand for concise confirmation signals. Third, the meaning of “all correct” itself was useful in any context.
Allen Walker Read’s research is also worth reading in this light. He first proposed the etymology in 1941 and systematically proved it with six papers in 1963-64, yet he himself called it “a pleasant digression from my main work.”[13] The reason scholars had believed the wrong etymology for over 120 years is that “OK” felt so ordinary that no one felt the need to seriously trace its origins. The most common things go longest unexplained — a paradox in itself.
Today, “OK” belongs to no single language community. It has become an expression used equally by Arabic speakers, Hindi speakers, and Swahili speakers. The fact that only one survived from the original abbreviation craze — and that one has come to have the widest geographic distribution of any expression in the history of human language — shows that the survival of language depends far more on timing and infrastructure than on intention or quality.
