Where does OK come from?

The exact origin of OK is not clear, but the most popular theory states that OK was first written in the Boston Morning Post in March 1839 in reference to the Anti-Bell-Ringing Society passing through Boston on their way to New York. At that time, people started making fun of words and phrases and pronounced “oll correct” for “all correct”. Later, they shortened it to the initials ‘OK’.

However, the term gained popularity in 1840 during Martin Van Buren’s presidential campaign. Van Buren was nicknamed “Old Kinderhook”, as his place of birth was in Kinderhook, New York. He used "Vote for OK" as his campaign slogan. Although he lost the election, OK remained popular and spread.

Difference between OK and All right

‘OK’ is a synonym of ‘All right’ (sometimes referred to as alright, especially when speaking). The slight difference between ‘OK’ and ‘All right’ is that ‘All right’ seems more formal. This is because ‘All right’ is not considered as ‘slang’ like ‘OK’ is.

How is OK used?

The word 'OK' may be the most frequently spoken or typed word on the planet. It is a very common term used in the middle of a conversation when we agree with another.

The following is a simple example of a conversation:

Person 1: Hi
Person 2: Hello
Person 1: How are you?
Person 2: I am ok. What about you?
Chat continues…
Person 1: Now I have to go. I have some work pending on my office project.
Person 2: Ok
Chat end.

Instead of just saying OK, one should try to answer using different words, so that it is more formal, polite, or precise.

For example:
Person 1: Can you go buy some fruit for me?
Person 2: Yeah, sure. I’d be glad to. (Not just, “OK”)
