The Origin of Yey or Yay
The word yay has been used in English for hundreds of years. It is an exclamation. People use it to show joy, approval, or success. It appears in old English writing and poetry as a sound of happiness.
The spelling yey does not come from English history. It likely appeared because people spell words the way they hear them. Since yay sounds like “yay,” some people guess the spelling and write yey. Social media and texting helped spread this mistake.
