History

OK Day shines a light on one of the world’s most recognized words—“OK.” It all began in the 1800s when newspapers in the United States started playing with funny misspellings. One of them wrote “oll korrect” instead of “all correct” and shortened it to “OK.”

This appeared in print for the first time on March 23, 1839, in the Boston Morning Post. The word caught people’s attention and stuck around.

It didn’t stop there. During the 1840 U.S. election, supporters of presidential candidate Martin Van Buren called him “Old Kinderhook,” based on his hometown. They shortened it to “OK” and used it as a catchy campaign slogan.

The idea took off. From newspapers to politics, “OK” spread quickly. People across the country began using it in everyday talk.

Over time, it became a simple way to say things were fine, agreed on, or approved. Linguist Allan Metcalf, who studied the word in depth, decided to give it a special day.

In 2011, he created OK Day to celebrate the word’s journey from a joke to global fame. It’s now a reminder of how language can grow, change, and bring people together—even with just two little letters.

FAQ

How did the word “OK” become one of the most widely recognized terms in the world?

Linguists trace the written use of “OK” to an 1839 joke abbreviation for “oll korrect” in a Boston newspaper, followed by massive publicity in the 1840 U.S. presidential campaign for Martin Van Buren, nicknamed “Old Kinderhook.” From there it spread through telegraphy, business correspondence, popular media, and later broadcasting and film, until it was borrowed into many languages as a neutral, easy-to-pronounce signal of agreement or acceptance.

Is “OK” considered informal, and is it acceptable in professional writing?

Style guides generally view “OK” and “okay” as neutral and widely understood, but recommendations differ by context. Many newsrooms and dictionaries accept “OK” in both speech and writing, while some formal or academic style guides prefer more explicit verbs such as “agree,” “approve,” or “confirm” in contracts, reports, or scholarly work, where precision is more important than conversational tone.

What are the main ways “OK” is used in everyday language?

In ordinary speech, “OK” functions as a highly flexible discourse marker. It can signal agreement (“OK, I’ll do it”), acknowledgment (“OK” to show one is listening), transition to a new topic (“OK, next item”), evaluation (“The movie was OK” meaning acceptable but not great), or permission (“It’s OK if you’re late”). Linguists note that its meaning often depends more on tone, pitch, and context than on the word itself.

Why are there so many different stories about where “OK” comes from?

Over the years, people have proposed dozens of colorful origins for “OK,” linking it to Choctaw “okeh,” Scots “och aye,” French place names, African languages, and even Greek phrases. Detailed archival work by etymologist Allen Walker Read in the 1960s, however, showed that most of these stories emerged later as folk etymologies, while the documented 1830s Boston slang abbreviation “oll korrect” best fits the actual historical evidence.

Does the “OK” hand gesture mean the same thing in every country?

No. In many places the thumb-and-forefinger circle is understood as “OK” or “good,” but in others it can have very different or offensive meanings. Intercultural communication experts caution that it may be interpreted as a rude or obscene gesture in parts of Europe and Latin America, or carry political or extremist connotations in some recent contexts, so travelers are often advised to rely on a thumbs-up or spoken words instead.

Why do people write “OK,” “okay,” and “O.K.” differently, and is one form more correct?

Modern dictionaries typically list both “OK” and “okay” as standard spellings, while “O.K.” with periods reflects older print habits. Historical research suggests that “OK” as an abbreviation came first, with “okay” developing later as a phonetic spelling. In practice, choice of form is usually a matter of house style or personal preference rather than correctness.

How has digital communication changed the way people use “OK”?

In texting, chat, and social media, tiny differences in how “OK” is written often convey different attitudes. Capitalization, repetition, and added letters or punctuation, such as “ok,” “OK,” “okayy,” or “OK!!!,” can signal anything from neutral acknowledgment to enthusiasm or irritation. Conversation analysts note that this makes “OK” a useful but sometimes ambiguous tool for managing tone and relationships online.
