'''''OK''''' ({{IPAc-en|ˌ|oʊ|ˈ|k|eɪ|audio=en-us-okay.ogg}}), with spelling variations including '''''okay''''', '''''okeh''''', '''''O.K.''''' and [[#Variations|many others]], is an English word (originating in [[American English]]) denoting approval, acceptance, agreement, assent, acknowledgment, or a sign of indifference. ''OK'' is frequently used as a [[loanword]] in other languages. It has been described as the most frequently spoken or written word on the planet.<ref>{{cite news|url=http://www.scmp.com/news/world/article/1455146/ok-most-spoken-word-planet-marks-its-175th-anniversary|title=OK, 'most spoken word on the planet', marks its 175th anniversary|newspaper=South China Morning Post|date=23 March 2014|access-date=12 June 2022}}</ref>

The origin of ''OK'' is disputed; however, most modern reference works hold that it originated around Boston as part of a fad in the late 1830s of [[abbreviation|abbreviating]] misspellings; that it is an initialism of "'''oll korrect'''" as a misspelling of "all correct". This origin was first described by linguist [[Allen Walker Read]] in the 1960s.

As an [[adjective]], ''OK'' principally means "adequate" or "acceptable" as a contrast to "bad" ("The boss approved this, so it is OK to send out"); it can also mean "mediocre" when used in contrast with "good" ("The french fries were great, but the burger was just OK"). It fulfills a similar role as an adverb ("Wow, you did OK for your first time skiing!"). As an [[interjection]], it can denote compliance ("OK, I will do that"),<ref name=CK2021>{{Citation|title=OKAY across Languages: Toward a comparative approach to its use in talk-in-interaction|last=Couper-Kuhlen|first=Elizabeth|pages=131–173|chapter-url=https://benjamins.com/catalog/slsi.34.05cou|publication-date=2021|series=Studies in Language and Social Interaction|chapter=The prosody and phonetics of OKAY in American English|date=17 March 2021 |volume=34 |publisher=John Benjamins|doi=10.1075/slsi.34.05cou|isbn=9789027260284|s2cid=233623150|issn=1879-3983|editor-last=Betz|editor-first=Emma|editor2-last=Deppermann|editor2-first=Arnulf|editor3-last=Mondada|editor3-first=Lorenza|editor4-last=Sorjonen|editor4-first=Marja-Leena}}</ref> or agreement ("OK, that is fine"). It can mean "assent" when it is used as a [[noun]] ("the boss gave her the OK to the purchase") or, more colloquially, as a [[verb]] ("the boss OKed the purchase").

He also documented controversy surrounding ''OK'' and the history of its [[False etymology|folk etymologies]], both of which are intertwined with the history of the word itself. Read argues that, at the time of the expression's first appearance in print, a broader [[fad]] existed in the United States of "comical misspellings" and of forming and employing acronyms, themselves based on colloquial speech patterns:

{{blockquote|The abbreviation fad began in Boston in the summer of 1838 ... and used expressions like OFM, "our first men," NG, "no go," GT, "gone to Texas," and SP, "small potatoes." Many of the abbreviated expressions were exaggerated misspellings, a stock in trade of the humorists of the day. One predecessor of OK was OW, "oll wright."{{sfn|Adams|1985}}}}

The general fad is speculated to have existed in spoken or informal written U.S. English for a decade or more before its appearance in newspapers. ''OK''{{'}}s original presentation as "all correct" was later varied with spellings such as "Oll Korrect" or even "Ole Kurreck".

The term appears to have achieved national prominence in 1840, when supporters of the [[Democratic Party (United States)|Democratic political party]] claimed during the [[1840 United States presidential election]] that it stood for "Old Kinderhook", a nickname for the Democratic president and candidate for reelection, [[Martin Van Buren]], a native of [[Kinderhook (town), New York|Kinderhook, New York]]. "Vote for OK" was snappier than using his Dutch name.<ref name="The Economist"/> In response, [[Whig Party (United States)|Whig]] opponents attributed ''OK'', in the sense of "Oll Korrect", to the bad spelling of [[Andrew Jackson]], Van Buren's predecessor. The country-wide publicity surrounding the election appears to have been a critical event in ''OK''{{'}}s history, widely and suddenly popularizing it across the United States.

Read proposed an etymology of ''OK'' in "Old Kinderhook" in 1941.{{sfn|Read|1941}} The evidence presented in that article was somewhat sparse, and the connection to "Oll Korrect" not fully elucidated. Various challenges to the etymology were presented; e.g., Heflin's 1962 article.{{sfn|Heflin|1962}} However, Read's landmark 1963–1964 papers silenced most of the skepticism. Read's etymology gained immediate acceptance, and is now offered without reservation in most dictionaries.<ref name=AHD>{{cite web |title=OK or o·kay |url=https://www.ahdictionary.com/word/search.html?q=OK |work=American Heritage Dictionary of the English Language |publisher=Houghton Mifflin}} (good summary of the results of Read's six articles)</ref> Read himself was nevertheless open to evaluating alternative explanations:

{{blockquote|Some believe that the Boston newspaper's reference to OK may not be the earliest. Some are attracted to the claim that it is of American-Indian origin. There is an Indian word, okeh, used as an affirmative reply to a question. Mr Read treated such doubting calmly. "Nothing is absolute," he once wrote, "nothing is forever."<ref name="The Economist">{{cite news|title=Allen Read |url=https://www.economist.com/node/1403400 |access-date=29 December 2014 |newspaper=[[The Economist]] |date=24 October 2002}}</ref>}}

===Choctaw===
In "All Mixed Up", the folk singer [[Pete Seeger]] sang that ''OK'' was of [[Choctaw]] origin,{{sfn|Fay|2007}} as the dictionaries of the time tended to agree. Three major American reference works (Webster's, New Century, Funk & Wagnalls) cited this etymology as the probable origin until as late as 1961.{{sfn|Fay|2007}}

The earliest written evidence for the Choctaw origin is provided in work by the Christian missionaries [[Cyrus Byington]] and Alfred Wright in 1825.{{citation needed|date=October 2020}} These missionaries ended many sentences in their translation of the Bible with the [[Grammatical particle|particle]] "okeh", meaning "it is so",{{citation needed|date=October 2020}} which was listed as an alternative spelling in the 1913 Webster's.<ref name=okeh>{{cite web |url=http://www.thefreedictionary.com/okeh |title=okeh |work=Webster's Revised Unabridged Dictionary |year= 1913 |access-date=29 December 2014 |via=The Free Dictionary by Farlex |url-status=dead |archive-url=https://web.archive.org/web/20141229203357/http://www.thefreedictionary.com/okeh |archive-date=2014-12-29}}</ref>

Byington's ''Dictionary of the Choctaw Language'' confirms the ubiquity of the "okeh" particle,{{sfn|Byington|1915}} and his ''Grammar of the Choctaw Language'' calls the particle ''-keh'' an "affirmative contradistinctive", with the "distinctive" o- prefix.{{sfn|Byington|1870|p=14}}

{{blockquote|Subsequent Choctaw spelling books de-emphasized the spellings lists in favor of straight prose, and they made use of the particle[,] but they too never included it in the word lists or discussed it directly.  The presumption was that the use of particle "oke" or "hoke" was so common and self-evident as to preclude any need for explanation or discussion for either its Choctaw or non-Choctaw readership.{{sfn|Fay|2007}}}}

The [[Choctaw language]] was one of the languages spoken at this time in the [[Southeastern United States]] by a tribe with significant contact with African slaves.<ref>{{cite book|first=Robert Elliot |last= Flickinger |year=1911 |title=The Choctaw Freedmen and The Story of Oak Hill Industrial Academy|url=https://www.gutenberg.org/files/23321/23321-h/23321-h.htm|publisher=gutenberg.org}}</ref> The major language of trade in this area, [[Mobilian Jargon]], was based on Choctaw-Chickasaw, two [[Muskogean]]-family languages.

Arguments for a more Southern origin for the word note the tendency of English to adopt loan words in [[language contact]] situations, as well as the ubiquity of the OK particle. Similar particles exist in native language groups distinct from Iroquoian ([[Algonquian (language)|Algonquian]], [[Cree]] cf. "[http://www.creedictionary.com/search/index.php?q=ekosi&scope=1 ekosi]").

===West African===
An early attestation of the particle 'kay' is found in a 1784 transcription of a North Carolina slave, who, seeking to avoid being flogged, explained being found asleep in the canoe he had been ordered to  bring to a certain place to pick up a European exploring near his newly-purchased property :

{{blockquote|Kay, massa, you just leave me, me sit here, great fish jump up into da canoe, here he be, massa, fine fish, massa; me den very grad; den me sit very still, until another great fish jump into de canoe; but me fall asleep...{{sfn|Smyth|1784|pp=1:118–121}}}}

A West African (Mande and/or Bantu) etymology has been argued in scholarly sources, tracing the word back to {{Clarify|date=September 2023|reason=Which? Wolof and Bantu are utterly unrelated and spoken 2000 km apart.|text=the [[Wolof language|Wolof]] and [[Bantu languages|Bantu]]}} word ''waw-kay'' or the [[Mande languages|Mande]] (aka "Mandinke" or "Mandingo") phrase ''o ke''.{{citation needed|date=September 2023}}

David Dalby first made the claim that the particle ''OK'' could have African origins in the 1969 Hans Wolff Memorial Lecture. His argument was reprinted in various newspaper articles between 1969 and 1971.{{sfn|Cassidy|1981}} This suggestion has also been mentioned by Joseph Holloway, who argued in the 1993 book ''The African Heritage of American English'' (co-written with a retired missionary) that various West African languages have near-homophone discourse markers with meanings such as "yes indeed" or which serve as part of the [[Backchannel (linguistics)|back-channeling]] repertoire.<ref name="Yngve, Victor page 568"/>{{sfn|Holloway|Vass|1993}} Frederic Cassidy challenged Dalby's claims, asserting that there is no documentary evidence that any of these African-language words had any causal link with its use in the American press.{{sfn|Cassidy|1981}}

The West African hypothesis had not been accepted by 1981 by any etymologists,{{sfn|Cassidy|1981}}<ref name="onlineetym">{{cite web|url=http://www.etymonline.com/index.php?term=ok|title=Online Etymology Dictionary}}</ref><ref name="lighter">Lighter, Jonathon, (1994).

===Alternative etymologies===
A large number of origins have been proposed. Some of them are thought to fall into the category of [[False etymology|folk etymology]] and are proposed based merely on apparent similarity between ''OK'' and one or another phrase in a foreign language with a similar meaning and sound.  Some examples are:
* A corruption from the speech of the large number of descendants of Scottish and [[Ulster Scots people|Ulster Scots]] (Scots-Irish) immigrants to North America, of the common Scots phrase ''och aye'' ("oh yes").<ref>{{cite journal |last1= Read |first1= Allen W |year= 1964 |title= The folklore of "O.K." |journal= American Speech |volume= 39 |issue= 1| pages= 5–25 |jstor=453922 |doi=10.2307/453922}}</ref>
* A borrowing of the [[Greek language|Greek]] phrase {{lang|el|όλα καλά}} ({{Transliteration|el|''óla kalá''}}), meaning "all good".{{sfn|Weber|1942}}

==Early history in print==
[[Allen Walker Read]] identifies the earliest known use of ''O.K.'' in print as 1839, in the edition of 23 March of the ''[[Boston Morning Post]]''. The announcement of a trip by the Anti-Bell-Ringing Society (a "frolicsome group" according to Read) received attention from the Boston papers. Charles Gordon Greene wrote about the event using the line that is widely regarded as the first instance of this strain of ''OK'', complete with [[Gloss (annotation)#In linguistics|gloss]]:

{{blockquote|The above is from the ''[[Providence Journal]]'', the editor of which is a little too quick on the trigger, on this occasion. We said not a word about our deputation passing "through the city" of Providence.—We said our brethren were going to New York in the Richmond, and they did go, as per Post of Thursday. The "Chairman of the Committee on Charity Lecture Bells," is one of the deputation, and perhaps if he should return to Boston, via Providence, he of the Journal, and his ''train''-band, would have his "contribution box," et ceteras, ''o.k.''—all correct—and cause the corks to fly, like ''sparks'', upward.}}

Read gives a number of subsequent appearances in print. Seven instances were accompanied with glosses that were variations on "all correct" such as "oll korrect" or "ole kurreck", but five appeared with no accompanying explanation, suggesting that the word was expected to be well known to readers and possibly in common colloquial use at the time.

Various claims of earlier usage have been made. For example, it was claimed that the phrase appeared in a 1790 court record from [[Sumner County, Tennessee]], discovered in 1859 by a [[Tennessee]] historian named [[Albigence Waldo Putnam]], in which [[Andrew Jackson]] apparently said "proved a bill of sale from Hugh McGary to Gasper Mansker, for a Negro man, which was O.K.".<ref>[https://jacksonianamerica.com/2010/12/09/ok-o-k-or-okay/ Jacksonian America: "OK, O.K. or Okay?"] [https://books.google.com/books?id=9DjMSsxUR_UC&q=%22proved+a+bill+of+sale%22&pg=PR1 "History of Middle Tennessee" by A.W. Putnam, 1859, page 252]</ref> The lawyer who successfully argued many Indian rights claims, [[Felix S. Cohen]], supported the Jacksonian popularization of the term based on its Choctaw origin:
{{blockquote|When Andrew Jackson popularized a word that his Choctaw neighbors always used in their councils to signify agreement, the aristocrats he threw out of office, always grasping at a chance to ridicule backwoods illiteracy, accused him of abbreviating and misspelling "All Correct". But O.K. (or okeh, in Choctaw) does not mean "all correct"; it means that we have reached a point where practical agreement is possible, however far from perfection it may lie.<ref>{{cite journal |first=Felix S. |last=Cohen |title=Americanizing the White Man |journal=The American Scholar |volume=21 |issue=2 |date=Spring 1952 |pages=177–191 |jstor=41206885 }}</ref>}}

David Dalby brought up a 1941 reference dating the term to 1815. The apparent notation "we arrived ok" appears in the hand-written diary of William Richardson traveling from Boston to New Orleans about a month after the [[Battle of New Orleans]].{{sfn|Heflin|1941|p=90}} However, Frederic Cassidy asserts that he personally tracked down this diary, writing:
{{blockquote|After many attempts to track down this diary, Read and I at last discovered that it is owned by the grandson of the original writer, Professor L. Richardson, Jr., of the Department of Classical Studies at Duke University. Through his courtesy we were able to examine this manuscript carefully, to make greatly enlarged photographs of it, and to become convinced (as is Richardson) that, whatever the marks in the manuscript are, they are not OK.{{sfn|Cassidy|1981}}}}

Similarly, [[H. L. Mencken]], who originally considered it "very clear that 'o. k.' is actually in the manuscript",{{sfn|Wait|1941}} later recanted his endorsement of the expression, asserting that it was used no earlier than 1839. Mencken (following Read) described the diary entry as a misreading of the author's self-correction, and stated it was in reality the first two letters of the words ''a h[andsome]'' before noticing the phrase had been used in the previous line and changing his mind.{{sfn|Mencken|1945|p=275}}

Another example given by Dalby is a Jamaican planter's diary of 1816, which records a black slave saying "Oh ki, massa, doctor no need be fright, we no want to hurt him".<ref>{{cite news |first=David |last=Dalby |date=8 January 1971 |title=O.K., A.O.K and O KE; The Remarkable Career Of an Americanism That Began in Africa |url=https://www.nytimes.com/1971/01/08/archives/ok-aok-and-o-ke-the-remarkable-career-of-an-americanism-that-began.html |access-date=10 September 2013 |newspaper=[[The New York Times]] |page=31}}<br />{{*}}{{cite news |first=David |last=Dalby |title=The Etymology of O.K. |newspaper=The Times |date=14 January 1971}}</ref> Cassidy asserts that this is a misreading of the source, which actually begins "Oh, ki, massa ...", where ''ki'' is a phrase by itself:

{{blockquote|In all other examples of this interjection that I have found, it is simply ''ki'' (once spelled ''kie''). As here, it expresses surprise, amusement, satisfaction, mild expostulation, and the like. It has nothing like the meaning of the adjective OK, which in the earliest recorded examples means 'all right, good,' though it later acquires other meanings, but even when used as an interjection does not express surprise, expostulation, or anything similar.{{sfn|Cassidy|1981}}}}

==Variations==
Whether this word is printed as OK, Ok, ok, okay, or O.K. is a matter normally resolved in the style manual for the publication involved. Dictionaries and style guides such as ''[[The Chicago Manual of Style]]'' and ''[[The New York Times Manual of Style and Usage]]'' provide no consensus.<ref>{{cite web|url=http://www.grammarphobia.com/blog/2008/09/im-ok-youre-okay.html |title=I'm OK, you're okay |publisher=Grammarphobia |date=11 September 2008 |access-date=12 June 2011}}</ref> Whilst most variants have descended from the root "OK", "okay" predominates in edited English as it permits easier modification (e.g. by pluralising).<ref>{{Cite encyclopedia |year=2022 |title=okay; OK; O.K. |encyclopedia=[[Garner's Modern English Usage]] |publisher=[[Oxford University Press]] |location=Oxfordshire |url=https://www.oxfordreference.com/display/10.1093/acref/9780197599020.001.0001/acref-9780197599020-e-6402 |url-access=subscription |access-date=2025-01-15 |last=Garner |first=Bryan A. |edition=5th}}</ref>

|[[Arabic]]
|اوكي or اوك
|[[Arabic]] speakers also use the word widely, particularly in areas of former British presence like Egypt, [[Iraq]], Israel, Jordan, and Palestine. The prevalence of the term in the Arab world can be attributed to the prevalence of American cinema and television. It is pronounced just as it is in English but is very rarely seen in Arabic newspapers and formal media.{{citation needed|date=June 2024}}

| OK
|In Mainland China, the native term {{Lang-zh|c=好|p=hǎo|labels=no}} (literally: "good") is more often used instead, saying "OK" is usually reserved for when communicating with foreigners. However, the term tends to be modified into "OK了" (OK le) to better fit [[Mandarin language|Mandarin]] grammar. (The "了" indicates a change of state; in this case it indicates the achievement of consensus.) It is also somewhat humorously used in the "spelling" of the word for karaoke, "[[wikt:卡拉OK|卡拉OK]]", pronounced "kah-lah-oh-kei" (Mandarin does not natively have a syllable with the pronunciation "kei"). On computers, OK is usually translated as {{lang-zh|c=确定|p=quèdìng| labels=no}}, which means "confirm" or "confirmed".{{citation needed|date=June 2024}} In [[Taiwan]], ''OK'' is frequently used in various sentences, popular among but not limited to younger generations. This includes the aforementioned "OK了" (Okay le), "OK嗎" (Okay ma), meaning "Is it okay?" or "OK啦" (Okay la), a strong, persuading affirmative (similar to English's "Alright, cool"), as well as the somewhat tongue-in-cheek yes/no construction "O不OK?" (O bù OK?), "Is it OK or not?", again adopting the term into Chinese grammar.{{citation needed|date=June 2024}}

[[File:OK Sign.jpg|thumb|right|upright=0.5|alt=Closeup of fingers with the thumb and index finger forming a circle and the other fingers extended.|Okay sign]]
In the United States and much of Europe a related [[gesture]] is made by touching the index finger with the thumb (forming a rough circle) and raising of the remaining fingers.<ref name=FGuide>Armstrong, Nancy & Melissa Wagner. (2003) ''Field Guide to Gestures: How to Identify and Interpret Virtually Every Gesture Known to Man.'' Philadelphia: Quirk Books.</ref> It is not known whether the gesture is derived from the expression, or if the gesture appeared first. The gesture was popularized in the United States in 1840 as a symbol to support then-presidential candidate and incumbent vice president Martin Van Buren. This was because Van Buren's nickname, Old Kinderhook, derived from his hometown of Kinderhook, NY, had the initials O.K.<ref name=FGuide/> Similar gestures have different meanings in other cultures, some offensive, others devotional.<ref name="aol">[https://www.aol.com/article/2010/07/26/dangerous-body-language-abroad/19554303/ Dangerous Body Language Abroad] {{Webarchive|url=https://web.archive.org/web/20170425000711/https://www.aol.com/article/2010/07/26/dangerous-body-language-abroad/19554303/ |date=25 April 2017 }}, by Matthew Link.

''OK'' is used to label [[Button (computing)|buttons]] in [[Dialog Box#Application modal|modal dialog boxes]] such as [[error message]]s or print dialogs, indicating that the user can press the button to accept the contents of the dialog box and continue. When the dialog box contains only one button, it is almost always labeled ''OK''. When there are two buttons, they are most commonly labeled ''OK'' and ''Cancel''. ''OK'' is commonly rendered in [[upper case]] and without punctuation: ''OK'', rather than ''O.K. or'' ''Okay.''  The ''OK'' button can probably be traced to user interface research done for the [[Apple Lisa]].<ref>{{cite web|url=http://www.folklore.org/StoryView.py?project=Macintosh&story=Do_It.txt&topic=Lisa |title=Apple user interface designers pick ''OK'' |publisher=Folklore.org |date=17 July 1980 |access-date=12 June 2011}}</ref>

The [[Forth (programming language)|Forth]] programming language prints ''ok'' when ready to accept input from the keyboard. This prompt is used on [[Sun Microsystems|Sun]], [[Apple Inc.|Apple]], and other computers with the Forth-based [[Open Firmware|Open Firmware (OpenBoot)]]. The appearance of ''ok'' in inappropriate contexts is the subject of some humor.<ref>

In the [[Hypertext Transfer Protocol]] (HTTP), upon which the World Wide Web is based, a successful response from the server is defined as ''OK'' (with the numerical code [[HTTP 200|200]] as specified in RFC 2616).  The [[Session Initiation Protocol]] also defines a response, ''200 OK'', which conveys success for most requests (RFC 3261).

Some [[Linux distribution]]s, including those based on [[Red Hat Linux]], display [[Booting|boot progress]] on successive lines on-screen, which include ''[&nbsp;OK&nbsp;]''.
